More Knowledge About Symptoms Of Syphilis



Syphilis is a sexually transmitted infection caused by Treponema pallidum – a specific type of bacteria called a spirochete. Syphilisis characterized by four stages: primary, secondary, latent, and tertiary.
After becoming infected with syphilis, there is an incubation period between of 9 to 90 days (the average being around 21 days) before the first signs and symptoms of the disease appear. Each stage of syphilis has characteristic signs and symptoms but any particular sign or symptom of may or may not be present.
Syphilis develops in four stages, each with a different set of symptoms.

Primary stage
During the primary stage of syphilis, a sore (chancre) that is usually painless develops at the site where the bacteria entered the body. This commonly occurs within 3 weeks of exposure but can range from 10 to 90 days. A person is highly contagious during the primary stage.
In men, a chancre often appears in the genital area, usually (but not always) on the penis. These sores are often painless.
In women, chancres can develop on the outer genitals or on the inner part of the vagina. A chancre may go unnoticed if it occurs inside the vagina or at the opening to the uterus (cervix). The sores are usually painless and are not easily seen.
Swelling of the lymph nodes may occur near the area of the chancre.
A chancre may also occur in an area of the body other than the genitals.
The chancre lasts for 28 to 42 days, heals without treatment, and may leave a thin scar. But just because the chancre has healed does not mean the syphilis is cured or that a person cannot pass the infection to others.

Secondary syphilis is characterized by a rash that appears from 4 to 10 weeks after the chancre develops and sometimes before it heals. Other symptoms may also occur, indicating that the infection has spread throughout the body. A person is highly contagious during the secondary stage.
A rash often develops over the body and commonly includes the palms of the hands and the soles of the feet.
The rash usually consists of reddish brown, small, solid, flat or raised skin sores that are less. But the rash may look like other more common skin problems.
Small, open sores may be present on mucous membranes. The sores may contain pus. Or moist sores that look like warts (called condyloma lata) may be present.

When syphilis has spread throughout the body, the person may have :
A fever of usually less than 101°F (38.3°C). A sore throat. A vague feeling of weakness or discomfort throughout the body.
Weight loss. Patchy hair loss, especially in the eyebrows, eyelashes, and scalp hair. Swelling of the lymph nodes.
Nervous system symptoms of secondary syphilis, which can cause headaches, stiff neck, vision or hearing problems, irritability, paralysis, unequal reflexes, and irregular (different-sized) pupils.

Tertiary (late) stage
This is the most destructive stage of syphilis. If untreated, the tertiary stage may begin as early as 1 year after infection or at any time during a person's lifetime. A person with syphilis may never experience this stage of the illness.
During this stage, syphilis may cause serious blood vessel and heart problems, mental disorders, blindness, nerve system problems, and even death. The symptoms of tertiary (late) syphilis depend on the complications that develop. Complications of this stage include:
Gummata, which are large sores inside the body or on the skin. Cardiovascular syphilis, which affects the heart and blood vessels. Neurosyphilis, which affects the brain or the lining that covers the brain. Congenital syphilis
Congenital syphilis refers to syphilis passed from a mother to her baby during pregnancy or during labor and delivery.  Preventive Services Task Force strongly recommend that all pregnant women be screened for syphilis because of the severe consequences of being pregnant while infected or having a child born with congenital syphilis. Screening should be done:3, 4

At the first prenatal visit for all pregnant women.
At the beginning of the third trimester of pregnancy and again at delivery for women who are at high risk of acquiring syphilis.
Congenital syphilis increases the risk of fetal death and medical complications in newborns. 

Syphilis enters the fetal blood system through the placenta, causing infection of the newborn or death of the fetus. Symptoms of congenital syphilis include:
A highly contagious watery discharge from the nose ("snuffles"). Painful inflammation of the bone coverings. Contagious rash that frequently appears over the palms of the hands and soles of the feet. Reduced red blood cells in the blood (anemia). Enlarged liver and spleen.
Swelling of the lymph nodes. Failure to grow and develop normally (failure to thrive).
Because there are other conditions with similar symptoms, an accurate diagnosis is important for treatment.

If untreated, an infected person will progress to the latent (hidden) stage of syphilis. The latent stage is defined as the year after a person becomes infected. After the secondary-stage rash goes away, the person will not have any symptoms for a time (latent period). The latent period may be as brief as 1 year or range from 5 to 20 years.
Often during this stage, an accurate diagnosis can only be made through blood testing, the person's history, or the birth of a child with congenital syphilis.

A person is contagious during the early part of the latent stage and may be contagious during the latent period when no symptoms are present.
About 20% to 30% of people with syphilis have a relapse of the disease during its latent stage.2 A relapse means the person was symptom-free but then started having symptoms again. Relapses can occur several times.
When relapses no longer occur, a person is not contagious through contact. But a woman in the latent stage of syphilis may still pass the disease to her unborn baby and may have a miscarriage or a stillbirth or give birth to a baby infected with congenital syphilis.

Combo Pack of 7 Tests, Keep You Into a Complete Secret


Accurate and rapid diagnosis of sexually transmitted diseases (STDs) is a major global public health priority, especially in the developing world. Since the emergence of HIV/AIDS, it has become even more critical to diagnose STDs early, not only to save lives but also to prevent the spread of life-threatening infections. 
The answer is accurate, easy and innovative technology from Inverness Medical 
Scientifically engineered for dynamic performance anywhere in the world, Determine allows the detection of the causative organisms of  HIV/AIDS, hepatitis B, hepatitis C, Chlamydia, Gonorrhea  and Syphilis to be undertaken simply and accurately. 
The simple two step tests require no power, no water, minimal training, just a fingerstick for sample collection and can be easily stored and transported.

Who should be tested? 
It is recommended that the following people who face a higher risk be tested :
# Drug addicts who inject drugs and have been sharing needles or syringes
# Use of unprotected blood products or transfusion with infected blood
# Healthcare peoples who take blood without precautions
# Prisoners
# Prostitutes
# Men and women with more than one sex partners
# Unprotected sex with infected persons
# The person who realizes, having been in contact with any of the objects, which spreads HIV.

# Orasure is a non-invasive, quick, accurate way to test for HIV-1 antibodies without blood, needles, or lancets.
# The only FDA approved HIV-1 collection device that may be legally marketed in the U.S.
# A complete diagnostic system that is approved for professional use.
# Orasure is a rapid HIV diagnostic tool with over 99% accuracy.

The ImmunoCheck HIV antibody test is a simple blood test which detects the presence of antibodies to HIV 1 and HIV 2. The HIV antibody is a protein naturally produced in the body in response to an infection by the HIV. The antibody screening test is important because it provides you with an early indication that you have been infected with the HIV. Early indication can help minimize the likelihood of developing an illness related to AIDS
However you need to know that the antibody test is not a test for the disease AIDS - it does not tell you if you have AIDS.
It will only show whether you have come into contact with the virus which may cause AIDS.

Chlamydia is a very common bacterial infection, affecting both men and women. Because Chlamydia is passed from person to person during sex (vaginal, anal and oral), it is known as a sexually transmitted infection (STI or STD). Chlamydia is the UK's most prevalent sexually transmitted infection and is caused by a tiny bacterium, Chlamydia trachomatis. Although Chlamydia is easily treated (b y a short course of antibiotics) it is a problematic disease because, in the early stages of infection, about 75% of women and up to 50% of men do not have any symptoms. 
When Chlamydia is diagnosed it is easily treated and cured. However, left untreated Chlamydia can spread infection to the cervix and fallopian tubes and ultimately lead to infertility: Chlamydia is the most common preventable cause of infertility in women. If you are pregnant and have Chlamydia, the infection can also be passed on to your baby. In men, Chlamydia can cause epidydimitis (inflammation of the reproductive area.)

Hepatitis B surface antigen (HBsAg) is a protein antigen produced by HBV. This antigen is the earliest indicator of acute hepatitis B and frequently identifies infected people before symptoms appear. HBsAg disappears from the blood during the recovery period. In some people (particularly those infected as children or those with a weak immune system, such as those with AIDS), chronic infection with HBV may occur and HBsAg remains positive.
Home Bio Test Hepatitis B rapid test determines if antibodies to the hepatitis B virus exist in your body. This test is easy-to-use in your own home and guarantees complete confidentiality.
The Silent Killer, Hepatitis B is a growing public health concern. Home Bio Test gives you a way to obtain a confidential answer to the question of your own Hepatitis status.

The HCV Ab (also called Anti-HCV) test detects the presence of antibodies to the virus, indicating exposure to HCV. These tests cannot tell if you still have an active viral infection, only that you were exposed to the virus in the past. The test is reported as “positive” or “negative.” 
Home Bio Test Hepatitis C rapid test determines if antibodies to the hepatitis B virus exist in your body. This test is easy-to-use in your own home and guarantees complete confidentiality.
The Silent Killer, Hepatitis C is a growing public health concern. Home Bio Test gives you a way to obtain a confidential answer to the question of your own Hepatitis status.

Gonorrhea (Neisseria gonorrhoeae) is a very common STD; Gonorrhea is a purulent inflammation of mucous membrane surfaces caused by a sexually transmitted microorganism, Neisseria gonorrhoeae. Virtually any mucous membrane can be infected. This bacterial infection may at first cause a slight discharge from the vagina, penis, or anus. If the Gonorrhea infection is not treated, it can lead to sterility and other complications.
This Home Bio Test Gonorrhea Test is a rapid direct binding test for the visual detection of gonorrhea antigen in both men & women; using a secretory specimen and urine from the urogenital system, used as an aid in the diagnosis of gonococcus infection with the latest in Colloidal Gold Technology

Syphilis (Treponema Pallidum) the first symptoms of Syphilis infection may go undetected. The initial symptom is a chancre; it is usually a painless open sore that usually appears on the penis or around or in the vagina. It can also occur near the mouth, anus, or on the hands. If untreated, syphilis may go on to more advanced stages. 
The Syphilis Home Self test Kit is an at-home FDA approved doctor recommended test that offers over 99.9% accuracy.

Get For Your Personal Rapid Chlamydia Test



Chlamydia trachomatis infection is the most prevalent sexually transmitted infection worldwide; thus, rapid detection and treatment are crucial to prevent further transmission. Investigators assessed the performance of the Chlamydia Rapid Test using self-collected vaginal swab specimens from women. The gold standard of comparison was polymerase chain reaction testing of first-void urine specimens.

Chlamydia, caused by the bacterium Chlamydia trachomatis, is the most common sexually-transmitted bacterial infection in the UK, particularly amongst sexually active men and women aged 16-24 years.
In the majority of cases, the disease is asymptomatic in both men and women. If symptoms show, they may include discharge or pain when passing urine for men. Recent research suggests that, if untreated – even when no symptoms show – it may be a cause of reduced fertility. In women, it can lead to even more serious complications, such as pelvic inflammatory disease, chronic pelvic pain and ectopic pregnancy.

Screening has recently shown that in some parts of Britain, 10 per cent to 20 per cent of young adults have chlamydia.
Chlamydia can be cured, but unfortunately it often produces no symptoms in either men or women, so it can remain undetected.

Some women may experience: cystitis, change in vaginal discharge, mild lower abdominal pain.
These are very 'non-specific’ symptoms and can be caused by other infections and diseases. If you go to a GP or family planning doctor with these symptoms, make sure you have a chlamydia test. You are entitled to ask for the test if you aren't offered it.
In men, chlamydia often causes of discharge from the penis. Sometimes it can cause mild irritation at the tip of the penis that disappears after two or three days.
Many men will wait to see if the discomfort goes away. While the discomfort may disappear, the man can still harbour the infection.
If in doubt, get tested. Otherwise, you could put yourself at risk of inflamed and swollen testicles, and pass chlamydia on to your partner.

Once diagnosed, Chlamydia can be treated easily with a one-off antibiotic pill. However, until now, male rapid tests for Chlamydia have been relatively inaccurate and involved urethral swabs, which can cause discomfort.
The Chlamydia Rapid Test, a urine test can be used with minimal training. It is designed to be used in conjunction with FirstBurst, a device for collecting the first voided urine from men. FirstBurst collects six times the amount of Chlamydia bacteria compared to a standard urine sample to boost the test's sensitivity and gives the results in less than an hour.

Infections Associated with AIDS




Because people with AIDS have weakened immune systems, they're more prone to infections, called opportunistic infections. Opportunistic infections are caused by organisms that typically don't cause disease in healthy people but affect people with damaged immune systems. These organisms attack when there's an opportunity to infect.
Deterioration of the immune system is caused by the decline in CD4+ T cells, which are key infection fighters. As soon as HIV enters the body, it begins to destroy these cells.

Opportunistic Infections: Brain
Cryptoccoccal Menigitis — This is a yeast-like fungus infection that usually involves the brain and lungs, although it can affect almost any organ. The fungus that causes this condition is found in soil throughout the world. It is most common in soil contaminated by bird droppings. This disease most often occurs when a person's CD4+ T cell count falls below 100 cells per cubic millimeter of blood.

Use Hiv Saliva Test The Right For You


Many people live with the myth, that HIV and its harmful components are present in the saliva of a HIV positive person. Hence, kissing or sharing food with the patient can be contagious due to the presence of HIV in saliva. However, this is not true. Though the saliva might carry HIV viral RNA or proviral DNA, they are not harmful, when they reside in the human saliva.

The saliva does not carry HIV that could be infectious or contagious. This is because; the saliva does not offer a very favorable condition for the sustenance of HIV. In fact, saliva is a good agent of destroying this virus. It carries special antibodies that fight the HIV components. The antiseptic and "hypotonic" property of saliva is conditioned to destroy any foreign cell that is present in the mouth. It works as a natural defense mechanism in our body.

HIV requires a good quantity of salt for its survival. Therefore, blood gives HIV the most favorable environment for propagation. Saliva, on the contrary, deactivates 90% of the HIV- infected leukocytes, due to lack of salt. Leukocytes or the blood cells, which help in the transmission of HIV to the mucosal surface, fail to succeed in their purpose. The HIV in saliva expands and bursts, due to lack of salt.

Facts About HIV



- HIV (human immunodeficiency virus) infects cells of the immune system.
Infection results in the progressive deterioration of the immune system, breaking down the body's ability to fend off infections and diseases. AIDS (Acquired immune deficiency syndrome) refers to the most advanced stages of HIV infection, defined by the occurrence of any of more than 20 opportunistic infections or related cancers.

- You can't catch HIV from just being around a person or having casual contact with someone who is infected

- HIV infection is not carried in sweat or tears. It also can't be transmitted through water fountains, phones, toilet seats or clothes.

- HIV can be transmitted in several ways. HIV can be transmitted through:

* unprotected sexual intercourse (vaginal or anal) or oral sex with an infected person;
* transfusions of contaminated blood;
* the sharing of contaminated needles, syringes or other sharp instruments;
* the transmission between a mother and her baby during pregnancy, childbirth and breastfeeding

- It's not just homosexual people who need to be tested. Every one can get HIV.

- Combination antiretroviral therapy (ART) prevents the HIV virus from multiplying in the body
If the reproduction of the HIV virus stops, then the body's immune cells are able to live longer and provide the body with protection from infections.

- A person can't catch HIV from mosquitoes or any other bug bites or stings.

Gonorrhea Prevention (2)







Early Detection

Scientists haven't yet developed a vaccine or other way to prevent gonorrhea. You can avoid the disease by abstaining from sex or engaging in it with a monogamous, uninfected partner.

You can reduce, but not eliminate, your risk of getting gonorrhea by practicing safe sex.


The U.S. Preventive Services Task Force (USPSTF) recommends gonorrhea screening for all sexually active women who have risk factors for gonorrhea.

If you engage in high-risk sexual behaviors, you may want to consider being tested once a year for gonorrhea even though you don't have symptoms. Testing will allow gonorrhea to be quickly diagnosed and treated. This helps reduce the risk of transmitting gonorrhea and avoid complications of the infection. Nowadays Gonorrhea testing is made easy with The Home Bio Gonorrhea Test. The test is an easy to use, accurate and reliable assay that will detect antibodies to the bacteria that cause gonorrhea present on swab samples collected from the cervix or the urethra. The result is available within minutes – in the privacy of your own home.

The U.S. Centers for Disease Control and Prevention (CDC) also recommends screening for pregnant women who engage in high-risk sexual behaviors to prevent them from transmitting gonorrhea to their babies. If a pregnant woman is at high risk for gonorrhea, she may be tested again during the third trimester before delivery, to prevent transmitting the infection to her newborn.

Several gonorrhea tests can be used to detect or confirm an infection. Your doctor will collect a sample of body fluid or urine to be tested for gonorrhea bacteria (Neisseria gonorrhoeae). Most tests give results within a few days.

Other sexually transmitted infections may be present with a gonorrhea infection. Your doctor may recommend testing for:

Teens & HIV Test 2




Approximately 1.1 million Americans are living with HIV/AIDS, and more than 56,000 become infected with HIV every year. One-third of them are between the ages of 13 and 29. That means at least two teenagers and young adults in this country are infected with HIV every hour of every day. But many young people still do not think they are personally at risk for HIV.

When teens in the United States become infected with HIV, it usually happens in one of two ways:

1. By sharing needles used to inject drugs or other substances (including needles used for injecting steroids, tattooing, piercing, and body art). If the person who has used the needle is infected with HIV, his or her blood on the needle can infect anyone else who uses the same needle.

2. Through unprotected sex including anal, vaginal, and oral sex. This can happen when body fluids such as semen, vaginal fluids, or blood from an infected person get into the body of someone who is not infected. Everyone who has unprotected sex with an infected person is at risk of contracting HIV, but people who already have another sexually transmitted disease (STD) are even more at risk.

Children can be infected with HIV if an infected pregnant woman passes the virus to her unborn child. Treating the mother and child around the time the baby is delivered, delivering by cesarean section, and avoiding breastfeeding can reduce the baby's risk of infection.

If people with HIV get treated, they can live long, relatively healthy lives — just as people who have other chronic diseases like diabetes can. But, as with diabetes or asthma, there is still no cure for HIV and AIDS.
Pediatricians should offer routine HIV testing to adolescents at least once before they are 16 to 18 if the local prevalence of the virus is greater than 0.1%, according to a new policy statement from the American Academy of Pediatrics.

If the local community prevalence is lower, pediatricians should offer the test to all sexually active patients as well as to those with other risk factors, such as drug use, according to Patricia J. Emmanuel, MD, of the University of South Florida, and colleagues on the academy's Committee of Pediatric AIDS.

The recent introduction of rapid HIV tests makes screening less invasive, although the gold standard remains detection of HIV antibody in serum, followed by confirmatory tests with Western blot or immunofluorescent assay.

Teens & HIV Test 1



Today, many doctors only offer testing to patients they deem at risk, such as prostitutes, drug addicts and homosexual men. But since 2006, the U.S. Centers for Disease Control and Prevention have urged everybody older than 13 to get an HIV test regardless of risk factors in areas with many undiagnosed cases.
Making HIV testing a routine part of health care for adolescents and adults aged 13–64 years is one of the most important strategies recommended by CDC for reducing the spread of HIV.

HIV testing is also an integral part of the National HIV/AIDS Strategy to prevent the spread of HIV and improve health outcomes for those who are already infected.
State and local education agencies and schools are essential partners in this effort.

Why HIV Testing Is Important? 
More than 1 million persons in the United States are living with HIV infection; of those, many do not know they are infected. HIV usually proceeds to AIDS in the absence of treatment, but newer drugs can keep that from happening for many years. And knowing you're infected may also help stem transmission of the disease to others -- a benefit that isn't seen with cancer screening, for instance.

Learning one’s HIV infection status is an important part of prevention. Studies show that people who know they are infected are far less likely to have unprotected sex than those who do not know. Early diagnosis of HIV infection and linkage to care enable people to start treatment sooner, leading to better health outcomes and longer lives.

About HIV Test (2)






Rapid HIV tests

OraQuick HIV-1/2 rapid test kit
These tests are based on the same technology as ELISA tests, but instead of sending the sample to a laboratory to be analysed, the rapid test can produce results within 20 minutes.

Rapid tests can use either a blood sample or oral fluids. They are easy to use and do not require laboratory facilities or highly trained staff.

All positive results from a rapid test must be followed up with a confirmatory test, the results of which can take from a few days to a few weeks.

Antigen test (P24 test)
Antigens are the substances found on a foreign body or germ that trigger the production of antibodies in the body. The antigen on HIV that most commonly provokes an antibody response is the protein P24. Early in HIV infection, P24 is produced in excess and can be detected in the blood serum (although as HIV becomes fully established in the body it will fade to undetectable levels).

P24 antigen tests are not usually used for general HIV diagnostic purposes, as they have a very low sensitivity and they only work before antibodies are produced in the period immediately after HIV infection. They are now most often used as a component of 'fourth generation' tests.

Fourth generation tests
Some of the most modern HIV tests combine P24 antigen tests with standard antibody tests to reduce the ‘diagnostic window’. Testing for antibodies and P24 antigen simultaneously has the advantage of enabling earlier and more accurate HIV detection.

About HIV Test (1)




HIV antibody test

HIV antibody tests are the most appropriate test for routine diagnosis of HIV among adults. Antibody tests are inexpensive and very accurate. The ELISA antibody test (enzyme-linked immunoabsorbent) also known as EIA (enzyme immunoassay) was the first HIV test to be widely used.

How do antibody tests work?
When a person is infected with HIV, their body responds by producing special proteins that fight infection, called antibodies. An HIV antibody test looks for these antibodies in blood, saliva or urine. If antibodies to HIV are detected, it means a person has been infected with HIV. There are only two exceptions to this rule:

Babies born to HIV infected mothers retain their mother's antibodies for up to 18 months, which means they may test positive on an HIV antibody test, even if they are actually HIV negative. Normally babies who are born to HIV positive mothers receive a PCR test (see below) after birth. Some people who have taken part in HIV vaccine trials may have HIV antibodies even if they are not infected with the virus.

Most people develop detectable HIV antibodies within 6 to 12 weeks of infection. In very rare cases, it can take up to 6 months and there are nearly always very particular reasons for antibodies developing so late such as other auto-immune disorders. It is exceedingly unlikely that someone would take longer than 6 months to develop antibodies.

What is a window period?
The ‘window period’ is a term used to describe the period of time between HIV infection and the production of antibodies. During this time, an antibody test may give a ‘false negative’ result, which means the test will be negative, even though a person is infected with HIV. To avoid false negative results, antibody tests are recommended three months after potential exposure to HIV infection.

A negative test at three months will almost always mean a person is not infected with HIV. If an individual’s test is still negative at six months, and they have not been at risk of HIV infection in the meantime, it means they are not infected with HIV.

It is very important to note that if a person is infected with HIV, they can still transmit the virus to others during the window period.

HIV & Pregnancy



Doctors recommend all pregnant women get tested for HIV. Medications are available to prevent the spread of the virus to your unborn baby. In addition, steps can be taken during delivery to prevent spreading the infection. Some studies show a woman can further reduce the risk of spreading the virus to her baby by having acesarean section before her water breaks. Moreover, your health care provider can take steps to help you stay healthy longer.

There are a number of interventions that can reduce the risk of HIV transmission between a couple when attempting to conceive a child.


Orasure is a non-invasive, quick, accurate way to test for HIV-1 antibodies without blood, needles, or lancets. It's the only FDA approved HIV-1 collection device that may be legally marketed in the U.S. It has a complete diagnostic system that is approved for professional use.Orasure is a rapid HIV diagnostic tool with over 99% accuracy.


If the woman is HIV positive and the man is HIV negative
An HIV positive woman and an HIV negative man can conceive without HIV transmission occurring by using artificial insemination (the process by which sperm is placed into a female's genital tract using artificial means rather than by natural sexual intercourse). This simple technique provides total protection for the man, but does nothing to reduce the risk of HIV transmission to the baby.

If the man is HIV positive and the woman is HIV negative
Sperm washing is a process used to prevent HIV transmission from an HIV positive man to his partner during conception. Sperm washing involves separating sperm cells from seminal fluid, testing these cells for HIV, then inserting the cells into the woman's womb (intrauterine insemination), or directly into the egg (in vitro fertilisation or intracytoplasmic sperm injection). Sperm washing is a very effective way to reduce the risk of HIV transmission during conception, but it is not widely available and can be difficult to access, even in well resourced countries. Alternatives to sperm washing have been researched, such as the method of using PrEP and timed intercourse when the HIV-positive male partner is taking antiretroviral drugs.

If both man and woman are HIV positive
When both partners are HIV positive, it might still be sensible for them not to engage in frequent unprotected sex, because there might be a small risk of one re-infecting the other with a different strain of HIV.

If a pregnant woman is infected with HIV, she can transmit the virus to her baby during pregnancy, labour and delivery, or breastfeeding. Without treatment, around 15-30 percent of babies born to HIV-infected women will become infected with HIV during pregnancy and delivery. A further 5-20 percent will become infected through breastfeeding.

HIV Testing for Pregnant Women

In many countries across the world, women are tested for HIV during pregnancy. There are a number of important reasons for this:

Assessing Your HIV or STD Risk



How does HIV relate to chlamydia and gonorrhea?
All STDs, including chlamydia and gonorrhea, are spread by having unprotected sex. HIV, itself, is an STD! If you have had unprotected sex, it is even more likely that you might be infected with chlamydia or gonorrhea than with HIV because these STDs are easier to catch than HIV.

What type of test would be done?
AIDS tests are now made simple, easy and are available right from the privacy of your own home. OraQuick is an antibody test that provides results in 20 minutes. The blood, plasma or oral fluid is mixed in a vial with developing solution, and the results are read from a sticklike testing device. Usually detects HIV 1 and HIV 2. Orasure is an HIV test that uses mucosal transudate from the tissues of cheeks and gums. It is an antibody test that first employs ELISA, then western blot.

When can I get my results?
OraQuick is an antibody test that provides results in 20 minutes.

What is chlamydia?
Chlamydia (cla-mid-ee-ah) is a sexually transmitted disease caused by a type of bacteria called Chlamydia trachomatis. Chlamydia can infect men, women, and children. It is passed from one person to another during vaginal, anal, and oral sex. Chlamydia can also be spread to the eyes by touching vaginal fluids or semen and then touching your eyes. Babies of infected mothers can get eye and lung infections during delivery.

Common Q&A of Oral Aids Test



What is the significance of the Food and Drug Administration’s (FDA) approval of the OraQuick rapid HIV test for oral fluid on March 26, 2004?
The FDA has approved the OraQuick Advance HIV1/2 Antibody Test for use with oral fluid and for use on plasma specimens. Until now, the test, manufactured by OraSure Technologies, Inc., was approved only for whole blood specimens. This is the only rapid HIV test to be approved in the US by the FDA for use with oral fluid.

What is the difference between the OraQuick Advance Rapid HIV 1/2 Antibody Test for oral fluid and the OraQuick Rapid HIV-1 Antibody Test for blood approved by the Food and Drug Administration in November 2002?
The FDA approved the new version of the test for the detection of HIV-2 antibodies and for use with additional types of specimens. Until now, the OraQuick rapid HIV antibody test required a whole blood specimen, either from a fingerstick or a tube of blood. The OraQuick Advance test can now be used with oral fluid specimens taken from the mouth, with plasma, and with whole blood. Additionally, the new version of the test can be performed in a wider range of operating temperatures (59°F to 99°F).

Is the OraQuick test a saliva test?
No. The test uses oral fluid, which is slightly different from saliva. To perform the test, the person being tested for HIV gently swabs the device completely around the outer gums, both upper and lower, one time around and inserts it into a vial containing a developer solution. After 20 minutes, the test device will indicate if HIV antibodies are present in the solution by displaying two reddish-purple lines in a small window in the device.

What does a reactive or preliminary positive result mean?
A reactive HIV test result on oral fluid is a preliminary positive and needs to be confirmed by an additional, more specific test to verify whether HIV antibodies are present.

How well does the test work?
In the clinical studies by the manufacturer, the OraQuick oral fluid test correctly identified 99.3% of people who were infected with HIV (sensitivity) and 99.8 % of people who were not infected with HIV (specificity). The Food and Drug Administration expects clinical laboratories to obtain similar results.

What Are The Symptom of Hiv Infection



Some people who contract HIV experience very strong symptoms, but others experience none at all. Those who do have symptoms generally experience symptoms similar to the common cold or flu: fever, fatigue, and, often, rash. Other common symptoms can include headache, swollen lymph nodes, and sore throat. These symptoms can occur within days or weeks of the initial exposure to the virus during a period called primary or acute HIV infection. Many infections that are not HIV can cause similar symptoms, including mononucleosis, viral hepatitis, other sexual transmitted infections, and viral hepatitis. Stress and anxiety can also produce similar symptoms in some people, even though they do not have HIV.

Because of the nonspecific symptoms associated with primary or acute HIV infection, symptoms are not a reliable way to diagnose HIV infection. Testing for HIV antibodies is the only way to know whether you have been infected; however, the HIV antibody test only works after the infected person's immune system develops antibodies to HIV. During the "window period" between the initial infection and the period in which antibodies are detectable (which can be from 2 weeks to 6 months, but is usually around 3 months), standard HIV antibody testing may be negative, even though a person is infected--it is too early for the antibody test to be positive. However, HIV can be diagnosed during this window period with a test that looks for the HIV virus itself, and not the body's response to it.

Once the primary or acute infection is over, most people do not experience any visible symptoms for another 8-10 years.
