This article details laboratory tests for diagnosing human immunodeficiency virus (HIV) infection and monitoring its progression. It covers methods detecting antibodies, antigens, and viral sequences for both HIV-1 and HIV-2.

Area of Science:

  • Virology
  • Immunology
  • Clinical Diagnostics

Background:

  • Two primary types of human immunodeficiency virus (HIV), HIV-1 and HIV-2, are recognized.
  • Both HIV-1 and HIV-2 infections can progress to Acquired Immunodeficiency Syndrome (AIDS).

Purpose of the Study:

  • To describe laboratory diagnostic tests for HIV infection.
  • To outline methods for monitoring HIV disease progression and therapeutic efficacy.
  • To explain principles for differentiating between HIV-1 and HIV-2.

Main Methods:

  • Detection of host antibodies against HIV.
  • Detection of viral antigens.
  • Analysis of viral nucleotide sequences.
  • In vitro cultivation of the virus.
