"The window period is the time between potential exposure to HIV infection and the point when the test will give an accurate result. During the window period a person can be infected with HIV and be very infectious but still test HIV negative."

"The HIV test window is a period of about 14-21 days, but in some cases up to 12 weeks. This is the period during which a blood sample from an HIV patient will show no sign of HIV, meaning he will test negative for the infection. After the HIV window period, the virus can be detected in a blood sample. Encouraging donors to give full disclosure when filling out donor questionnaires is important as those who report behavior potentially risky (IV drug use, or sex with someone who has HIV) are restricted from donating."

One of the most prevalent concerns of dealing with blood or blood products is the possible transmission of HIV. Understanding things such as test window and what it means is crucial. The interviewer wants to know what knowledge you have of HIV and that you have an understanding of why 'test window' time is important.

"The HIV test window is used to describe the time between when the patient becomes infected with HIV until the appearance of the detectable antibodies of the virus."
