To avoid all the stress and anxiety, due to HIV, it is advised to confirm the HIV status from your sexual partners. In âcase, it is highly impossible, then there is no alternative but to undergo screening tests for HIV, at regular intervals âuntil 3 to 6 months, as determined by a doctor. â
HIV is a incurable disease and prevention or early detection and proper treatment is the only available options âcurrently. Unprotected sexual intercourse does increase the risk of infection. â
Once you are exposed to HIV, you will need surveillance period of 3 months to 6 months, at least to make sure that âyou are not HIV infected. â
The only measures for HIV detection is via blood tests to check for antibodies to HIV (Commonly called ELISA tests) âand also NAAT (Nucleic acid assay tests , eg PCR).
Getting a negative HIV antibody test, in the early days, does not âmean that you are free of infection. It is definitely possible that you may develop antibodies at a later date. Hence âretesting at a later date after 12 weeks is definitely adviced to get a conclusive result. â
The best test to detect HIV within the window period (before 4 weeks) is the HIV DNA PCR. This is a test, used to detect âthe presence of Proviral DNA, synthesized from HIV viral RNA, using the âreverse transcription âtechnology. This test is a much more sensitive test than HIV RNA PCR, and can be done after 2 weeks âof exposure, to get a reliable and conclusive result. â
In case you have done a HIV antibody ELISA test, after 12 weeks, post exposure, and it is negative, it is certainly possible that you are HIV negative, and the results are conclusive.
