Detecting human immunodeficiency virus (HIV) involves initial screening for HIV antibodies, followed by confirmatory tests for accuracy. This review covers current HIV testing methods and their limitations.

Area of Science:

  • Virology
  • Immunology
  • Medical Diagnostics

Background:

  • Human immunodeficiency virus (HIV) types 1 and 2 are linked to acquired immunodeficiency syndrome (AIDS).
  • Accurate detection of HIV infection is crucial for patient management and public health.
  • Current diagnostic strategies rely on detecting the body's immune response to the virus.

Purpose of the Study:

  • To review current screening and confirmatory testing procedures for HIV infection.
  • To discuss the limitations associated with existing HIV diagnostic methods.

Main Methods:

  • Review of existing scientific literature on HIV diagnostic assays.
  • Analysis of common screening tests for HIV antibodies.
  • Evaluation of confirmatory testing strategies for positive screening results.

Main Results:

  • Screening tests detect antibodies to HIV proteins in serum samples.
  • Confirmatory tests are essential to validate positive screening results.
  • Both screening and confirmatory methods have inherent limitations that impact diagnostic accuracy.

Conclusions:

  • The diagnosis of HIV infection relies on a multi-step testing approach.
  • Understanding the limitations of current HIV tests is vital for accurate interpretation of results.
  • Further advancements in HIV testing may address existing diagnostic challenges.
