It’s now been 6 months post pep and I tested yesterday. Usually my results come back the morning after but they haven’t yet and it’s causing me concern. What are the chances my results have changed since 6 weeks? 

Thank you.

Now knowing there was indeed a risk what do you think about the pep, 2 missing doses, my negative 13 day post pep RNA test and negative 41 day post pep ag/ab test and now my late and resultless 6 month post pep test? What should I expect the results to be? Thank you. 

The question immediately after yours (no. 9880) also asked about missing doses of PEP. There is little no chance that missing a few doses reduces its effectiveness in preventing HIV; and your negative test results at 13 and 41 days also are nearly 100% proof you were not infected.

I'll be happy to comment one more time if you would like to post your latest test result when you have it -- but not until then.

I’ve seen similar situations as mine answered on here where people test at 12 days (rna) and 40 days (ag/ab) post pep and you say they’re conclusive and don’t need further testing, why is my situation different? Why are my tests at 13 days (rna) and 41 days (ag/ab) post pep only NEARLY conclusive and not entirely conclusive like theirs? Do you think it’s likely my result will change? Sorry but the difference in your answer for me as well as late test results are making me very anxious right now. 

In addition, we consider the overall odds. In your case, under one in a million chance you acquired HIV. PEP effectiveness, let's say around 90%. That makes the odds you have HIV, after PEP, one chance in 10 million. If we also assume your tests so far are "only" 99% conclusive, not 100%, your odds of having HIV become one chance in a billion. That's zero for all practical purposes, even though the test itself isn't quite conclusive.

I did not ask you to post your test result. It was an offer, to say you are welcome to do so if you wish. ("I'll be happy to comment one more time if you would like to post your latest test result when you have it.") We regularly make the same offer; it does not imply we expect a positive test result. (Among thousands of questions over 20 years in this and our preceding forum, not one person turned out to have caught HIV. You will not be the first!)

Threads normally are closed after two follow-up exchanges, and we're there. I'll leave this open a few more days, so you can post your pending test result if you decide to do so. However, any further comment other than that will result in closure of this thread without reply. OK?

Thank you and thank you for being patient.
