Had sex 7 days ago. I went in for an HIV test and a pregnancy test. Could they be accurate or should I recheck next week?

Had sex 7 days ago. I went in for an HIV test and a pregnancy test. Could they be accurate or should I recheck next week?

Re-check: According to the legend you are a male so lack of pregnancy did not need to wait for laboratory confirmation. However, if you are a female or asking on behalf of someone.... Both tests are a little early to be definitive. Pregnancy test should be repeated in 1 week and HIV in a few weeks and again at 3 and 6 months. Be safer in the future. Tests and anxiety not worth it. ...Read more

Can healthy people get false positive ELISA HIV test? If so why?

Yes, it is possible: Some people may have a biologically false-positive test for hiv, when tested by elisa. Such people usually have a negative or indeterminate confirmatory test, the western blot.

A friend had hiv test at 6 months last exposure negative,now he had a pos for hiv-2 at 7 months.He also did a pcr at 4 months.can it be false positive?

Probably false pos: HIV-2 is very rare outslide the area of west Africa where it originated (Cameroon), although I don't know about Albania for sure. The PCR should have picked up HIV-2 as well as HIV-1. So your freind's HIV-2 test probably is false positive. He should see an infectious diseases or HIV expert to sort it out. ...Read more
