Variable: Most people who get infected test positive by 3 months, a bit sooner with duo test. Occasionally some people do get a positive test for a year after infection. HIV nucleic acid test is positive sooner and more specific. See this site for more info. http://www.cdc.gov/ActAgainstAIDS/basics/testing.html
