SORRY pleas don't answer that.
I have already asked and it was answered.
thank you Teak.
I'm sorry but is 3months like 12weeks.... are 12 weeks long enough for a conclusive test?
You are not in that catagory and need not worry about it. Your 3 month test would be conclusive.
what causes the very few people that do become positive after the 12th week?
You've been here long enough to know that 3 months is conclusive and the CDC guidelines was changed from 6 months to 3 months in 2004. No you don't need to take an unapproved test. Get your conclusive test and be done with it. Your 11 week test isn't going to change.
