Some doctors say hiv test after 45 days is conclusive, then why wait till 3 months?

Seroconvert is 4-6 weeks. Doctors say most people show antibodies after 4 weeks according to a source from new york .

Because you could sero-convert, moron.

Well, because getting tested earlier than 3 months may result in an unclear test result, as an infected person may not yet have developed antibodies to HIV.

Most people develop these antibodies within 3 months of infection. In rare cases, it can take up to 6 months. (By the way, it would be extremely uncommon to take longer than 6 months for antibodies to develop.)

So, it's better to wait for at least 3 months after the last time you were at risk before taking the test. It's also recommended by some to take the test again after 6 months, just to be sure.

HIV tests detect antibodies 鈥?the immune system's response to infection. It can take up to three months after infection to develop antibodies. This is called the "window period." During the window period, HIV tests can come back negative even though the person has the virus. HIV can be passed to other people during the window period.

and some people don't it can take up to 90 days it's called the window period where the virus is undetected

if you test using the fourth generation tests (antigen+antibody) then 6 weeks is enough
