Can you be HIV positive after a negative test a year and a half after exposure?

It is possible. HIV testing is a delicate process because a person may be infected with the virus but not test positive until several months after infection.
Example: A person is exposed to HIV and waits two months, then gets a routine HIV test. Because the individual is in their "window period" (the amount of time it takes for someone to develop enough HIV antibodies to test positive) they may have a negative test result despite having been infected.
HIV test sensitivity varies. When getting tested for HIV, it is important to know the sensitivity of the test being used because follow-up testing may be required to provide a conclusive result.
