PCR RNA is currently accurate after 24 to 72 hours.....

this test is also known as a viral load.

Western blot can deliver early predictions at 21 to 28 days as well, NYU did a seroconversion study that basically mapped which proteins will test positive first in Western Blots when ELISA isn't reacting yet.
Don't obsess over the wrong things.  Life isn't about your numbers, it isn't about this forum, it isn't about someone's opinion.  It's about getting out there and enjoying it.   I am a person with HIV - not the other way around.

Doesn't matter what result one gets from a PCR (DNA or RNA) test, it still has to be confirmed with a positive antibody and WB result. Just sayin'... ::)

what's the point of a test like this when we still are testing less than 20% of the population.  What's the point when so manybpeople are still having unsafe sex.  I'm sure Tiger's wife thought she was in a committed relationship...ROTFLMAO.   She had every reason to expect it but was a fool if she didn't actually protect herself.  No doubt Tiger was looking out for her.

The point of this test is to differentiate between antibodies produced through a vaccine and antibodies produced due to the presence of hiv in the body. I guess you didn't bother to follow the link V provided. We already have tests that will detect antibodies in the first few weeks, and those tests are pretty much standard now days. You still have to test out to three months for a conclusive negative result, but a positive will show within the first six weeks in the majority of cases.

HIV-SELECTEST is a serodiagnostic EIA, containing p6 and gp41 peptides, designed to differentiate between vaccine-induced antibodies and true infections. A Rapid Test version of the HIV SELECTEST was developed. Both assays detected HIV antibodies in men and women within 2-4 weeks of infection, with sensitivity similar to third generation EIAs.(from the link above)

pacerintl,

Right now the test is used in research, especially when testing antibodies for those brave hiv- folk that are entering hiv vaccine trials. The test is able to distinguish between those antibodies generated by infection and those that are produced by the vaccine being tested.

Also, when this test becomes available for general use, those folks who are worried about an unsafe situation, will be able to determine their status quickly and hit the virus early and hard with the newer meds that are available.

Ann,

Your correct, a PCR test does have to be confirmed with a positive antibody test. That's how my doctor confirmed my status back in 91. This HIV-SELECT test will get to the final answer as to infection a lot quicker and with greater confidence.
