HIV NAAT Test & Hepatitis

Oct 7, 2009

I just took a negative Hiv test (@ 7 weeks with rapid Elisa) at the AHF clinic here in Los Angeles.

They then drew two vials of blood for a NAAT test.

Does having chronic Hepatitis B increase the probability of a false positive NAAT test?

I will donate for all of your good work here.

Many thanks!

Response from Dr. Frascino


Having chronic hepatitis B would not increase the probability of false-positive NAAT tests; however, nucleic acid testing in general can lead to some false-positive results. The best HIV-screening test remains an FDA-approved HIV-antibody test taken outside the window period.

Thank you for your donation to The Robert James Frascino AIDS Foundation ( It is urgently needed and warmly appreciated. In return I'm sending you my good-luck/good-health karma that your definitive HIV test remains negative. Your negative rapid test at seven weeks is extremely encouraging.

Good luck. Be well.

Dr. Bob

negative test 12 weeks!
