I seen alot of other posts from reading about window period. Some Doctors says 3 months and other says 6 month and I have Hiv Dr told me 12 months too make extra sure. What is the 4ger test and 3 ger test

Most company's do not go by generation naming. They actually rename their tests. 4th generations are any new test such as your DUO tests. 3 generations are those that are used at most clinics. Testing at 3 months doesn't make a difference which test is used.

I don't understand this post.
