The HIV PCR is one of the most sensitive tests to detect HIV virus. It is usually done after 3 weeks of the suspected exposure. You have not specified clearly as to what tests you had done before which were positive. Please elaborate.

Dermatologist Dr. Gaurav Patel's  Response
hi
A standard antibody test (see above) looks for HIV antibodies in a person’s blood. These antibodies can take up to three months from the time of infection to appear, and so for an accurate HIV test, a person should wait three months since the time of suspected infection.
Some test centres may recommend testing again at six months, as in very rare cases it can take this long to develop antibodies.
However, in most cases it is not necessary.

u want to test in short period then antigen test are there.
A PCR test (Polymerase Chain Reaction test) can detect the genetic material of HIV rather than the antibodies to the virus, and so can identify HIV in the blood within two or three weeks of infection. The test is also known as a viral load test and HIV NAAT (nucleic acid amplification testing).
