Hi DR. Frascino:

I will make a donation. I am heterosexual male around 48.I had a possible exposure with a couple of CSW in canada a few weeks ago.It was vaginal and no oral. This is only exposure i ever had outside the committed relationship. There is lot of stress due to guilt. I had STD and HIV(antibody 3rd ge. EIA) test done at 4 weeks and then agian HIV(antibody 3rd gen. EIA) and Syphilis test done at 8 weeks after exposure.My question is how reliable are these tests at 8 weeks.The nurse at the clinic said it is greater than 99%. Is that true? Do I need further testing.


Response from Dr. Frascino


Canada has slightly different guidelines than the U.S. Centers for Disease Control and Prevention (CDC). The latter's guidelines recommend HIV screening at the three-month mark for a definitive result. That said, it is true that the vast majority of (but not all) HIVers will have detectable levels of specific anti-HIV antibody in their blood within four to six weeks after primary HIV infections and therefore test HIV-antibody positive.

I would advise:

1. Level with your "committed relationship" partner. It's not only the best way to deal with your guilt; it's also the right thing to do.

2. Repeat your HIV-antibody test at the three-month mark.

Thanks for your support of The Robert James Frascino AIDS Foundation ( It's warmly appreciated. In return I'm sending you my good-luck karma that your definitive three-month HIV-antibody test will remain negative. The statistical odds are all in your favor.

Good luck!

Dr. Bob

Woo Hoo or Uh Oh!
Some karma please
