Hiv P24 Test
HIV is also known as HIV/AIDS. Hiv infection is caused by a retrovirus....This retrovirus binds to CD4 cells (for the most part). You may detect the virus by several different methods. An elisa test (enzyme linked immunosorbent assay). You may also detect it by doing a test referred to as a western blot (a gel protein electrophoresis). Thirdly by pcr (polymerase chain reaction) which ...Read more
Had protected vaginal sex with CSW. How reliable is negative HIV p24 antigen combo test at 20 days mark? Also, getting results tomorrow for HIV RNA PCR at 19 days. Will that be conclusive if negative?
Pretty reliable: most people who turn positive would be positive at least borderline by day 14-20. There are uncommon cases of over 1 month to turn positive. NOte that the incidence of this is far lower than the liklihood of someone Totally Lying about What They are Doing !. Oh, sorry, that's for the antibody. The antigen/other measures of virus should be done TOGETHER with antibody. REALLY low risk of false negat ...Read moreSee 1 more doctor answer
Not widely used: The level of p24 antigen and the amount of virus (viral load) increase significantly soon after initial infection. It is during this time frame, before HIV antibody is produced, when the p24 test and the HIV antigen/antibody combination test are useful in helping to diagnose infection. About 2-8 weeks after exposure, antibodies to HIV are produced in response to the infection and remain detectable. ...Read moreSee 1 more doctor answer
Hiv p24 ag ab combo test at 28 days, 42 days and 62 days, some are negative.Quanto to be safe after 62 days?
Not a good test: P24 antigen testing is not the best way to rule out infection. The most sensitive test is a qualitative viral dna test, not usually performed. At 62 days HIV elisa may well be positive, if you were infected. Because sometimes antibodies are not formed until 90 days, you can complement by HIV RNA test that can detect down to 20 copies per ml of blood. ...Read more

I went for HIV test which is HIV 1/2 & p24 Combo test (CMIA) on 32 and 41 day of my last exposure, report says non reactive.
Is this 100% conclusive?
I got a tattoo. On 32nd day i went for HIV 1/2 & p24 Combo test (CMIA) and its came negative.
Is this conclusively?
How much i can trust this result.
Trust it: Proper sterilization of tattoo equipment is near-universal today. There is an HIV risk if the needle was recently used by another person. Just how much of a risk getting inked ever was for hepatitis C is unknown; other risky practices run with tattoo culture. Whatever exposure you may have had, the test is reliable at 32 days; human reporting error makes the false-negative rate unknowable. ...Read more
