The time between the moment when HIV enters a person's body and the moment when testing can detect the antibodies to HIV (3 to 6 months). During this window period, a person may test negative, even though he/she is infected with HIV and hence can infect other people.
the time between primary infection and the appearance of antibodies against an organism (seroconversion).
The period between the time someone becomes HIV infected to the moment HIV antibodies can be detected in their body.
Refers to the time between infection with HIV and when its antibodies can be detected in the blood (as short as six weeks but usually longer, up to six months for test purposes).
Time from infection with HIV until antibodies are detected.
In medicine, the window period for a test designed to detect a specific disease (particularly infectious disease) is the time between first infection and when the test can detect that infection. In antibody-based testing, the window period is dependent on the time taken for seroconversion.
