HIV screening test

The human immunodeficiency virus (HIV) attacks the cells of the immune system and causes acquired immunodeficiency syndrome (AIDS).

HIV1,2 Ag+Ab is the first test in the diagnosis of HIV infection. The method used in the ETCH Central Laboratory allows simultaneous measurement of the antigen and antibodies, which makes the test more sensitive in the early stages, compared to rapid HIV tests. The test gives a positive result starting from the 12th day after catching the infection. For confirmation of a positive result on the first HIV test, the sample is sent to a reference laboratory.
