The time it takes for a person who has been infected with HIV to seroconvert (test reactive) for HIV antibodies is commonly called the “window period”. The three-month window period is normal for approximately 95% of the population. The CDC has said that in some rare cases, it may take up to six months for one to seroconvert. If you feel any anxiety about relying on the three-month result, by all means you should have another test at six months.
