WHAT IS WINDOW PERIOD FOR AN ANTIBODY TEST?

Hello and thank you for using AIDS Vancouver as your source of HIV/AIDS related information.
 
The window period for a typical antibody test, which is often an ELISA (or 3rd Generation) test is between 4 weeks (28 days) and 3 months (84 days). Most people tend to develop detectable antibodies with 21-25 days. Even though most HIV infections are detected within this period, HIV guidelines still recommend that retesting be done at or after 12 weeks to consider a result as conclusive.
 
In addition, there is another common HIV test called a Rapid (or Point-of-Care) test which also detects antibodies. For this test the window period is the same as an ELISA test (4-12 weeks). The only difference between these two tests is the testing procedures and the time it takes to receive your results once the test has been performed.
 
I hope I've answered your question but if you have any further concerns please feel free to call or email us.
 
Take Care,
