Hi, I had a risky encounter 36 days ago. I have had some tests done. HIV RNA at 14 days and a fourth generation test at 28 days. Today at day 36 I took another RNA test and another 4th generation test. If these come back negative are they conclusive? So much conflicting info on internet. Thanks 

I forgot to mention the rna test at 14 days was negative and the 4th generation test at 28 days was negative. Waiting on results from today which is 36 days for the rna test and 4th generation test I took today

Welcome to the forum.---

Thanks doctor, I just want to be sure. I was not sure when the RNA test is conclusive so I did both the rna test again today along with the fourth generation. It seems you are confident I will be ok. I read the rna test is not conclusive till 28 days

Although the individual tests have certain times to become conclusive, the combination of negative RNA at 14 days and AgAb test at 28 days is conclusive. That's what we recommend commonly on this forum, and I would have advised against the additional tests, especially the repeat RNA test. In any case, you're home free now, which will be confirmed when you get the 36 day test results.---

Great, thanks. Last question, when is rna test conclusive? Thanks again

By itself, RNA is nearly conclusive (90-95%) at 14 days and virtually 100% by 3 weeks, according to most estimates. (That's all they are, estimates without conclusive data -- which is why various sources will give somewhat different times).---
