RNA PCR is for early detection, test at the 14 th day after the exposure backed up by an antibody test at the 12th week is good enough to rule out HIV.
DNA PCR at the 28th day after the exposure backed up by an antibody test at the 12th week is good enough to rule out HIV
Both are NAT tests and are highly sensitive.

It's an ELISA test.
These assays have demonstrated a high analytical sensitivity of detection that is most likely attributed to the combination of a third-generation format (antigen sandwich) for antibody detection and the ability to simultaneously detect HIV p24 antigen. To date, there are 8 commercial, combination antibody and antigen assays that have been developed and evaluated.
a pcr is used to moniter the already infected people, the cross contamination can give out false positive more often than an elisa, and even so a undetected viral load has to be followed by an antibody test at the 3 months mork, so pcr is a waste of money so go for an antibody test at 3 months mark
Those other tests you mention are all early detection tests,an elisa test will be enough at 126 days and a cheaper option aswell.
Can HIV ANTIBODY TEST(ELISA<HIV ! & ANTIBODY) test after 6 months fi fully conclusive????? I hb done ELISA test aftr 6 mnths of exposure???? Can I be 100% confident tat I m HIV negetive as the test came back non reactive with ANTIBODY 0.020 OD........will I have to test aftr ! yr?
Under what circumstances is a PCR-RNA and P24 test used and does that give you a more conclusive result?
can two steroid shots, one at 3 weeks after exposure and a second one 5 weeks after exposure and long term topical steroid use for eczema delay hiv antibody production and detection.
The PCR can give false positives, costs a lot, sometimes gives false negatives and is not easy to perform. You can have an undetectable viral load and test "negative" but still have the virus. This said, an antibody test is much more reliable overall because if you have antibodies they will show...hope this helps.
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.
I used to wait 3 months for the elisa test, but I found out my local clinic has a 30 day window period test. I also found out that an early detection test is now available at only 9-11 days after last contact. So my question is if I take the early detection test with the 9-11 day window period after waiting 12 days since last sexual contact, will I be able to rest easy on those results, or do I have to wait out the 30 days until the clinic will give me that test?

Hiye, this may seem a silly question but is the Elisa test that is used for HIV the same as the
