How and When to Get Yourself Tested Again?

HIV, like many infections, gets transferred from one host to another and the body tries to fight it. So initially, no test can detect HIV infection immediately.

The time between when a person has been exposed to HIV and when a test can tell for sure whether they have HIV is called the "window period." The window period can vary from person to person. Also, it depends on the type of test used for detection. There are many tests to detect HIV, some are described in brief here.

  1. 1st Generation - uses infected viral cell breakdown products as antigen.
  2. 2nd Generation - uses glycopeptides (recombinant antigens) from the HIV virus.
  3. 3rd Generation - synthetic peptides are used as antigens.
  4. 4th Generation - simultaneously detects the p24 antigen, HIV-1 and HIV-2 antibodies, and nucleic acid based tests.
