A member asked:

How accurate is pcr test for hiv after the 1st and 2nd week of exposure?

A doctor has provided 1 answer

Likely to be neg: It takes about 25 days following exposure for the hin nat to become positive. If positive, it is nearly 100% accurate. Negative test does not exclude HIV in the body.
