4 month neg HIV test brief unprotected encounter with female is this conclusive 3 2ndgenantibodies test neg three rapids neg and a PCR undetectable ?

Nucleic acid tests, like pcr, are used in testing donor blood. Although the basic tests can be extermely accurate there is a chance of false negatives due to the up to 6 month seroconversion time it takes to make antibodies. See my comment. ...Read more

By 3 months after exposure...97% of people will have antibodies to antigen. In rarer instances it may take up to 6 months to develop antibodies. After 6 months..99% of people exposed will have antibodies to viral antigens. Therefore the 3 to 6 months!!! ...Read more

HIV: Yes. Except for rare instances (and these are in some question), testing negative at 6 months ensures an absence of disease. If you want to be absolutely certain you can spend the money and have pcr for viral RNA done. This will guarantee you are negative if it is not detectable. ...Read more
