1 doctor agrees
In brief: Two tests
Not sure i would call it a "rule", but i would say that: 1.
One HIV negative test is never enough. 2. One is not HIV positive until: i. Hiv screen is positive, and ii. The screen is confirmed by a positive western blot of course there are a few nuances to this, but you will have to be more specific about your question.

There is an additional test used predominantly by doctors who suspect they are dealing with an acute HIV syndrome, and that is to measure for HIV nucleic acid in the blood. This is, however, expensive and only used in limited circumstances.
