The time between becoming infected and having detectable levels of antibodies in the blood is called the window period. For HIV, the window period is up to 3 months.
Development of detectable antibodies to HIV in the blood serum as a result of infection. It may take several months or more after HIV transmission for antibodies to the virus to develop. After antibodies to HIV appear in the blood, a person will test positive in the standard ELISA test for HIV.
