Re: Window period for DNA PCR

Hi, I agree with the other responders. The DNA-PCR is not as sensitive as modern serologies at the three month mark (the Johns Hopkins Guide indicates a maximum of 99% analytical sensitivity, in clinical practice the sensitivity is often a little lower). It has a much higher tendency to produce false positives than statndard serology. Moreover, the commercial Roche DNA-PCR-kit most widely used is mostly sensitive for HIV-1 subtype B. Even with the Roche 1.5 primers, there are subtype problems. So the baseline is that such testing should only be done in cooperation with an experienced infectious disease doctor with long-term experience with testing in the window period. You will have to test at the 3 months mark anyway. Take care and don't panic!
