Answer

Hi,

Any negative test (for HIV-antibody tests) or undetectable result (for HIV PCR tests) is encouraging. However, HIV-antibody tests taken prior to the three-month mark are not considered definitive or conclusive. It is true that the vast majority of HIV-infected folks will have detectable levels of anti-HIV antibodies in their blood within four to six weeks following primary HIV infection. PCR testing is not recommended for routine HIV diagnostic screening, due to the level of false positives, other technical considerations and cost.

Thanks for your support of The Robert James Frascino AIDS Foundation.

Good luck! Be well. Happy Holidays.

Dr. Bob
