Our Testing Methodology

We make use of an accredited laboratory which utilizes the HIV Proviral DNA test to obtain results at least 12 days after exposure to the virus. Our doctors will recommend a testing protocol based on your risk profile and exposure. In some cases, testing is not indicated at all. In others, a series of multiple tests are advised. The PCR test is an extremely sensitive test and can detect the presence of proviral DNA even if there are only a few copies of the proviral DNA in the blood specimen.

HIV Proviral PCR testing is not usually recommended for mass screening for HIV due to its high cost and slow turnaround time. However in certain special situations, where the patient's anxiety is extremely dysfunctional, this test may be used.

How Long Does It Take?

Specimens typically take as early as 3-4 days for a result.

Are The Results Accurate?

Testing can be done as early as 12 days after exposure, and gives close to 99.9% accuracy at least 28 days post-exposure. The PCR test result should not be taken in isolation, and our doctor will recommend a protocol which usually includes antibody testing subsequently at different stages post-exposure, in order to completely allay your anxiety.

Excerpt from US Communicable Disease Centre (CDC) Website:

How long after a possible exposure should I wait to get tested for HIV?

Most HIV tests are antibody tests that measure the antibodies your body makes against HIV. 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.” Most people will develop detectable antibodies within 2 to 8 weeks (the average is 25 days). Even so, there is a chance that some individuals will take longer to develop detectable antibodies. Therefore, if the initial negative HIV test was conducted within the first 3 months after possible exposure, repeat testing should be considered >3 months after the exposure occurred to account for the possibility of a false-negative result. 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.

Another type of test is an RNA test, which detects the HIV virus directly. The time between HIV infection and RNA detection is 9–11 days. These tests, which are more costly and used less often than antibody tests, are used in some parts of the United States.
