What test after high risk encounter ?
Apr 19, 2001

Dear sir, What test would you recommend at 3 months post high risk exposure: a RNA PCR( viral load ), or a DNA PCR. Which one of this is most accurate? What would you say about the acuracy of Ag P24 & ELISA Antibody both -ve after the 3 months exposure ( giving the fact that I've been ARS like symptomatic for almost 2 months now.) Would you think that a negative PCR test at 3 months is final ? Thank you very much, I'm looking forward to your answer.

Response from Mr. Kull

The only test that I would recommend three months following a high risk exposure would be an HIV antibody test (ELISA/Western Blot). Nothing beats the sensitivity and specificity of the antibody test after the window period has elapsed.

PCR tests are not licensed for diagnosing infection and lack the antibody test's accuracy. It is possible for a person who has been HIV infected to have an undetectable viral load (through PCR testing), even without medication. You are also more likely to have a false positive on PCR tests when compared to antibody tests.
