Both of my test results were non reactive.
All HIV tests, regardless of generation, are conclusive at 3 months post exposure. Therefore, your 5 month test was conclusively negative.
1st generation were highly unreliable and also needed a much longer window period (sometimes up to 6 months). It is difficult for me to talk about those as I am not the most experienced with them, I could help you more with 3rd or 4th generation tests.
If you have any doubt about those older tests, maybe you can simply get a rapid test or, if you are in the US, you could buy an Oraquick test. At this point, both those tests will be 100% conclusive and will use the current standard for testing.
Just one thing though, was the anal sex unprotected? Because if it was protected and condom did not fail, you were not at risk in the first place...
I was to anxious.... And scared I finally took an test in ICTC(Integrated counselling and Testing Center of India) I took the test at 25 weeks... I guess its 6 months .... Still they say the tests in ICTC are latest and are very sensitive and 3 months is conclusive... Hence he concluded I'm negative...... Thank u so much guys for ur support :) I love ya :).. Oh bdw 24 weeks is 6 months right?
Rapid comb test probably 2nd gen after 21 weeks..... Is it conclusive now? Or should I test at 24 weeks?
As I already told you in my first response, all HIV tests are conclusive at 3 months post exposure.
