HIV 4th generation test

Hello there.  I’m a bit confused about the window period of the HIV antibody/antigen test.  Some say 3 months (and that “most” people if they’re positive test positive at the 6 week mark) while others say 6 weeks.  I had an antibody/antigen test 45 days after my last dose of PEP and it was negative.  Is this conclusive?  Is it a true negative?  As part of a medical test, I also tested negative with another ag/ab HIV test at 51 days.  I look forward to hearing from you.

I never noticed any drug taking in this area I was in.  It’s an area with hotels and businesses.

I don’t know how ludicrous or plausible this will sound to you.  What I’ll say is that I get anxiety.  I don’t do drugs.  I fell asleep one night on some steps from drinking too much.  When I woke up I thought, what if someone injected me with HIV while I was asleep?  I never noticed any blood or needle marks.  I did have this brown mark on my hand.  I took a photo of it and showed it to a doctor recently and he said it looked like a bruise or like I’d gotten some kind of solvent on my skin.  I was in Asia at the time and only had to go to a chemist to get PEP and no questions were asked.

Ok, you had no risk. People don't inject others with hiv blood. This is a good time to evaluate whether you have a drinking problem, unless it was a rare night of heavy drinking.

Your PEP was a waste of time. The test was just a placebo, and there are no guidelines for placebo tests so it doesn't matter when you take the test. You wasted your time testing, and it is time to stop.
That's irrational thinking. No one could inject you intravenously without you knowing, particularly if they're not a medical professional, and no one is running around with syringes full of HIV+ blood.

Address your anxiety and drinking.
Thanks for everyone’s helpful responses.  I did read a story about how an HIV positive man dipped a  needle in his blood and then poked his wife with it while she was sleeping and gave her HIV.

STOP GOOGLING FOR DEATH.
You're doing this to yourself at this point. You Googled until you found something from 15 years ago in a newspaper widely known as the "Daily Fail" for its terrible, inaccurate reporting.  Even IF you found one instance, a one in 80 MILLION chance of something happening to you is absurd to even think about once, much less obsess over.

You can keep Googling if you want to, but we are not under any obligation to keep answering you and pretending that you might have had a risk for HIV. We are all volunteers and this is a waste of our time. We're not in the business of feeding anxiety.
Well, it was in other newspapers too but I get your point.  Thanks.
Sorry, I didn’t mean to waste anyone’s time.  I’ve been trying to find a psychiatrist for my anxiety.
It's an even worse problem when you have read so many crackpot disinformation newspapers that you say you read that a few times. The first step to peace is to stop googling cold turkey, and the second is to stop telling everyone what you read, since no one here will believe it. You aren't a researcher and either don't understand what you read or else you found a crackpot site.
No one here reads links of what posters claim they read.

Thanks.  I was thinking that I was in the clear and then a nurse said that some people have taken longer than 45 days to test positive with a 4th generation test. So, he said to wait for three months.

What did you do that caused a risk for hiv?

Depends. What was your risk that you went on PEP?

I've never heard anyone in this decade recommend testing out to longer than 6 weeks post-exposure or post-PEP, whichever event happens later. HIV experts say 4-6 weeks after your last dose.

3 months only applies to the standalone antibody test.

Out of curiosity, has anyone ever read anything that states that the 4th generation HIV (ag/ab) test is 90% accurate at 6 weeks to 45 days and 99 to 1oo% accurate at 3 months?  A nurse informed me that he found this information.  I can’t find these statistics anywhere. Everything I’ve read, reads, “95% accurate at 28 days and 99% accurate at 45 days.”  Ninety nine percent accuracy is deemed to be conclusive according to a few sites including “i base”.
Ok, you had no risk. People don't inject others with hiv blood.
The test was just a placebo, and there are no guidelines for placebo tests so it doesn't matter when you take the test.
There are thousands of diseases and conditions any of which you can get at any time with no warning.
It is abnormal for you to fixate on the one you can't get. I don't know why you keep coming back here asking for advice, since you haven't accepted what you were told.
Thank you but this was a question out of pure curiosity regarding the future. I certainly don’t hope to get myself in trouble again due to unsafe sex but I’m getting tired of all the conflicting evidence I hear/read.  
"It is abnormal for you to fixate on the one you can't get."
Now you're worrying about a maybe situation -  in future -  where you do something dumb and end up having a risk scenario?   That's called hiv fixation!
This is not a place where people with hiv fixation can dream up a fantasy situation, then expect others to humor your make believe nightmare. You have not accepted any advice here or from your doctors, yet you keep coming back asking more questions that you won't accept, which is ILLOGICAL.
Yes, I think I may have developed a phobia.
