Is it possible to get the wrong results when testing HIV?
The major concern with HIV testing that is inaccurate is when people test too early.
In order for an HIV test to be accurate, there have to be enough antibodies present for the test to pick up. If a person tests too soon after infection, the body may not have had time to develop antibodies which can be measured. In these cases, a test will return a negative result, when in fact the person is HIV positive.
