Here is all you need to know about the different types of HIV tests available and some considerations you should keep in mind. A rapid HIV test involves drawing a small amount of blood normally via a finger prick with a result usually available within 30 minutes.
There are three possible results; negative, reactive and invalid. These results are only preliminary and blood will still need to be collected from your arm and sent to a laboratory to confirm the result.
If you have contracted HIV, your immune system will start producing antibodies reacting to the virus within weeks following exposure. These antibodies are detected by the test, and if you test positive, another test will be done to confirm the result. It tests for quantities of a protein known as the p24 antigen, which is part of the HIV virus and produced in high amounts early on after contracting HIV. In Australia, most labs currently test for both HIV antibodies and the p24 antigen.
It involves collecting a few drops of blood from your finger and allowing the blood to dry on a test card. You then send the card away to get tested and wait around a week to get the result back.

I have got 18 antibody tests including a western blot test starting from my 38th day of exposure till the 85th day of exposure and all of them have come negative. My latest test was done after the 85th day of exposure in a private lab in India and the test was a HIV Tridot test and the result came back negative.
I have read conflicting information about the Tridot test on this forum. With due respect, Dr Sean has called the test a second generation test and said that it does not give accurate results till 6 months of exposure, while Teak has said it is a third generation test and result after 3 months 12 weeks is conclusive.
I have become paranoid about this after feeling relieved after a negative 12 week test. I have gone through a horrifying 12 weeks since my exposure and any information about the test will be helpful. Private labs in India don't seem to have the DUO tests which are spoken about so often on this forums. Also could you let me know: 1 If so many tests within the window period further delay the antibody formation and the window period duration subsequently increases?

Your question has no context because you did not put yourself at risk, This forum has assessed your situation as not a risk for HIV.On page 11, they state : "A negative result usually means that the person is not infected with HIV. In rare instances, a person with a negative or inconclusive result may be in the window period.

Persons at high risk who initially test negative should be retested 3 months after exposure to confirm results. Unfortunately when it comes to HIV testing, there are many potentially confounding variables, such as:. Differences in immune response from person to person, which can affect how long it takes to produce detectable levels of specific antibodies.Diagnosis and Testing of HIV Infection
Because missing an HIV diagnosis can have catastrophic consequences, organizations that formulate guidelines tend to err on the conservative side. Below is the CDC's most recent comment about testing.
As you can see, they continue to mention that in very rare cases it can take up to six months to develop antibodies to HIV. When deciding if three months is definitive or "definitive enough," HIV specialists take into account the likelihood of infection. The following are behaviors that increase your chances of getting HIV.
If you answer yes to any of them, you should definitely get an HIV test. If you continue with any of these behaviors, you should be tested every year. Talk to a health care provider about an HIV testing schedule that is right for you.
Have you injected drugs or steroids or shared equipment such as needles, syringes, works with others? Have you had unprotected vaginal, anal, or oral sex with men who have sex with men, multiple partners, or anonymous partners?
Have you exchanged sex for drugs or money? Have you been diagnosed with or treated for hepatitis, tuberculosis TBor a sexually transmitted disease STDlike syphilis? Have you had unprotected sex with someone who could answer yes to any of the above questions?
Both you and your new partner should get tested for HIV, and learn the results, before having sex for the first time. For women who plan to become pregnant, testing is even more important. If a woman is infected with HIV, medical care and certain drugs given during pregnancy can lower the chance of passing HIV to her baby. All women who are pregnant should be tested during each pregnancy.
It can take some time for the immune system to produce enough antibodies for the antibody test to detect, and this time period can vary from person to person. This time period is commonly referred to as the "window period. Even so, there is a chance that some individuals will take longer to develop detectable antibodies.
Ninety-seven percent of persons will develop antibodies in the first 3 months following the time of their infection.
In very rare cases, it can take up to 6 months to develop antibodies to HIV. These tests, which are more costly and used less often than antibody tests, are used in some parts of the United States.
