Window period and conclusive results

[phillipbaloo]

Hello everybody!

I had an unprotected anal sex with male (the highest risk category). I did the first test 41 days after the exposure and it came back negative. It was the 4th generation Ag/Ab Hiv test. In the lab where I did the test (I am from Serbia, South East Europe) they said that the window period for test which they use is between 6 and 8 weeks and they confirm that the test is the 4th generation.

1. Do all test of the 4th generation have the same window period (28 days)?

2. How conclusive is my result 41 days after the exposure?

3. Could the fact that I did test one day before the six-week period affect my result?

I am going to do test after 8 weeks but I feel very anxious about my further results.

The test you took is indeed conclusive at 28 days.  You've tested negative and that is good news. We are now closing this discussion. Best to you.

Do you think that all tests from the 4th generation have the same window period or it can depend on used technique or company which produce the test?

We consider 4 weeks test result conclusive test.

They are more conservative and we don't converse with them so don't know or care why they are different, because there are so many sites and countries that it would be full time job studying all of them.
