4th generation elisa testing after 44 days of exposure

Hi folks,
I've done an HIV Duo 4th gen test on a very reliable Lab 44 days of potential exposure (condom breakage on vaginal insertive sex with a friend). My result was fortunately negative.
I'm still scared anyway because I have 2 doubts:

1.
There are few informations about testing being conclusive with 3/6 months that make me anxious.
Are these informations outdated or unrelated to 4th gen tests?

2.
Is the antigen p24 still detectable by DUO test after 6 weeks?
I'm worried if my case could be late seroconversion (even if I didn't take PrEP and have no autoimmune disease) and as I read, the p24 levels decrease after the peak of infection. Can I trust in my test result and stop being paranoid?


Thanks for the attention and I'm sorry if there are english mistakes
I really admire and trust in your job.

The latest 4th gen tests are very sensitive and accurate.the p24 portion starts to show up as early as in 14 days, it is considered that the mean peak of p24 is at 28 days while the first antibodies start to appear. 44 days are enough to show either the p24 or the antibodies part (or both).

oh... I did... but there was an accident with it. When I took off the penis it was torn so I was exposed to risk for sure.
I'd like to know if my test result is reliable
Yes, it is absolutely reliable.  Even if your antigen levels had dropped by that time, the antibody portion of the test is very sensitive and is considered reliable at the point you took it.

Delayed seroconversion is largely a myth, blown out of proportion thanks to the internet.  The cases that were found were years ago, and were likely attributable to less sophisticated, less sensitive tests available at the time.  Trust your negative result and forget about this event.
Did you do vaginal penetrating with the torn condom? Or oral with the torn condom?
thanks CurfewX.
anxious, vaginal pen.
I just noticed it was torn when I took off.
