A member asked:
Is a hiv 4th generation test conclusive after 7 weeks of exposure? on this website there are some saying that the 4th generation window period is 4 weeks, 45days, 6 weeks, 3 months or even 6 months! is 7 weeks safe?

The antigen-antibody (AgAb, "4th generation") HIV blood tests are conclusive by 45 days (which some experts round off to 6 weeks). Usually they are accurate from 4 weeks on. It clearly is never necessary to go beyond 45 days, and 7 weeks therefore is always conclusive. But why does it matter so much? If uncertain, just have a test beyond 45 days. No big deal, right?
