HIV Description:

  • Testing detects HIV, which is the cause of AIDS.
  • Common tests used to determine the presence of antibodies to HIV include ELISA, Western blot, and immunofluorescence assay (IFA).
  • A single reactive ELISA test by itself cannot be used to diagnose HIV and should be repeated in duplicate with the same blood sample; if the result is repeatedly reactive, follow-up tests using Western blot or IFA should be performed.
  • A positive Western blot or IFA result is considered confirmatory for HIV.
  • A positive ELISA result that fails to be confirmed by Western blot or IFA should not be considered negative, and repeat testing should take place in 3 to 6 months.
