The window period is the time from infection until a test can detect any change. The average window period with HIV-1 antibody tests is 25 days for subtype B. Antigen testing cuts the window period to approximately 16 days and NAT (Nucleic Acid Testing) further reduces this period to 12 days.he average window period with HIV-1 antibody tests is 25 days for subtype B.

Different Types of HIV Tests. The two types of antibody tests most commonly used to detect HIV infection are the ELISA (enzyme-linked immunoassay) and Western blot tests. These tests are very accurate, but they are only able to detect HIV antibodies and not the HIV virus particle itself. 1  A process is followed to determine if you are HIV positive. 2  First, the ELISA test is performed. 3  If the ELISA test is negative for the detection of HIV antibodies, the test is reported as negative.
