Test 4th generation after 90 days of risk
May 19, 2010
Dear Doctor Bob. I send you congratulations from Brazil, because this site is very clear and objective.
Something missing in our country, even though we have a great service for testing and counseling, free condoms and drug distribution.
First I apologize for my writing probably wrong because I only speak the Portuguese language. My question is simple and straightforward. On January 29, 2010, had a sexual contact and risk, oral sex with a prostitute, a short time (I have a tooth open). I made two tests of antibodies 40 days and 60 days, rapid tests ELISA (link government offered the So Paulo state), both negative. With exactly 90 days of exposure did in a particular laboratory regulated by the Brazilian Ministry of Health, a 4th generation combo test (antibodies combo p24 antigen) were negative. With this result my case this proved negative, or do I have another test of antibody alone? The 4th generation test is final 90 days after the sexual risk.
I ask the understanding of any possible error in grammar, I hope the doctor has understood me and answered my question quickly. I want to end this story and then my life more carefully.
Thank you. God bless you.
Response from Dr. Frascino
Negative HIV-antibody tests out to 90 days following oral sex are considered conclusive and definitive.
WOO-HOO or, in Portuguese, "OBA!"
