You don't require testing but if you were to have one a p24combo test is 99% accurate at 4 weeks and 12 weeks is 100% conclusive.
And if i want to have a test ,how long after the incident is conclusive?
Not possible because it becomes inactive right away,it can't remain active outside the body.
Thank you for your answer ,but i mean his semen went into urethra before the Hiv could become inactive,I mean it is very soon.
Not an Hiv risk for 2 reasons,one is that Hiv becomes inactive as soon as it is exposed to air and secondly Hiv transmission takes place inside the body not outside of it.Your safe.
