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

Is it possible to have an HIV p24 antigen, HIV antibody, and HIV PCR accurate 5 weeks after exposure?
Yes in part: The tests that detect actual HIV virus, such a the HIV viral load (pcr), will likely be positive 5 weeks after an exposure that results in transmission of hiv. The HIV antibody test may still be undetectable. So, if you are very worried about acute hiv, it is very important to discuss with your health provider so they do the right tests. ...Read more
Oral thrush 14th day after possible HIV exposure.Is it ARS symptom? P24 Combo on13th day; index value 0.1& nonreactive.No other symptoms.How reliable?
Surprise: When the serology test was first used it was thought to be diagnostic. Eventually it was found that most people were positive.

Then the serology titre (concentrration) goes up as the organism becomes active. ...Read more

Yes, but...: ...this is your 3rd or 4th question because of worry about HIV in what (from another question) was an obviously low risk exposure. You appear to be irrationally concerned, and having trouble believing or accepting repeated reassurance. There's no point in repeated questions; the answers won't change. Consider counseling; I suggest it from compassion, not criticism. Good luck and stay safe. ...Read moreSee 1 more doctor answer
Can CMV virus and type 2 diabetes together make the HIV western blot and PCR viral load tests false positive for hiv?
Yes, theoretically: Yes, it is theoretically possible that someone could get acute retroviral syndrome upon reinfection with another strain of HIV. First of all, reinfection is very, very rare but not impossible. However, reinfection with a second strain (perhaps more powerful than the original strain) theoretically could cause an acute retroviral syndrome as it is a completely new infection altogether. ...Read more

HIV testing: There are several HIV tests. We usually check what is called an elisa blood/oral test. It's very sensitive & specific but misses early, early infection (<15-20 days). In us we confirm a + elisa w/a test called a western blot (looks for HIV specific proteins). Other countries just use elisa x2. For acute HIV infection we measure viral RNA in blood. Can be falsely + so needs expert evaluation. ...Read moreSee 1 more doctor answer
