Interpreting HIV 1 And 2 Antibody - Chromatography results


Interpretations

  • A negative HIV antibody test usually indicates that a person does not have HIV infection. A negative test only means that their is no evidence of disease at the time of the test. The HIV antibody tests does not detect an HIV infection soon after exposure, before the development of antibodies. Most people produce detectable levels of antibody 3 to 12 weeks after exposure. If someone is screened with an HIV antibody test too soon, the result may be negative despite the fact that the person is infected. For those who are at increased risk of HIV infection, it is important to get this screening test done frequently to check for possible exposure to the virus 
  • If someone tests positive on both the initial screening and supplemental testing, then that person is considered to be infected with HIV
