Is a negative HIV RNA test at 20 days after possible exposure somewhat reliable?

About 95%: Probably about 95% reliable. You should also have an antigen-antibody ("duo", "combo") test at 4-6 weeks. But probably all is OK: the average HIV transmission risk for a single episode of vaginal sex, if one partner is infected, is around once for every 1000-2000 exposures. ...Read more

Can the inst hiv-1/hiv-2 antibody rapid test be reliable after 62 days to possible HIV exposure? Test results were negative. Could this be reliable?

HIV Testing: No, unfortunately. For the routine HIV antibody tests you need a minimum of three months or 90 days and a safe view of six months.

However there is testing that is much more reliable. This is the HIV pcr dna testing. This test, if negative after 21 days post exposure is 100% accurate if negative. ...Read more

I had syphilis and got blowjob from HIV unknown status person. I did elfa test at 22nd day. It came negative. How reliable it is?

Get tested again: Even if you have a syphilis chancre, it's hard to get HIV from saliva. You're probably okay, but if you're very worried, get a pcr assay. The antibody assays may not turn by day 22. I'm glad to see that you're becoming more conscientious about your health -- the person who gave you syphilis could have given you HIV as well. Out of respect for yourself and others, please resume using condoms. ...Read more

Pcr is the gold standard and will give you the right answer before either of the others. I hope things turn out well, but having HIV is no longer a death sentence. Good luck, live and love responsibly, and keep taking a proactive approach to your health. ...Read more
