Hiv) the cdc states that the 4th antigen and antibody test window period is 18-45 days and the nat pcr test to be 14 - 33 days. if these tests are taken after the window periods, are they conclusive ? i am confused because some doctors say 12 weeks?

When infected with HIV the virus (antigen) will begin to replicate. Because of factors such as how much virus was received initially and the person's immune reaction, the time it takes for the virus to be detected can be quite variable. Development of antibodies to the virus will follow a similar period. Once detectable both the antigen AND antibody tests will remain positive until treated.

I dont understand hiv testing window period and why so many doctors and websites say 6 months even some say a year but CDC says 90 days on only antibody tests?some say antibody tests are unreliable there are millions who rely on 3 month guidelines??
As per CDC guidelines hiv window period is 6 weeks, is this applicable for both types of hiv 1 & 2 ? as per my understanding 4th generation antigen is only for hiv 1 and only left with antibody which is recommended to test at 3 months?
