About this test

What is this test for?

The combination of antigen and antibody testing enables earlier identification of infection compared to antibody-only assays. Prompt detection supports timely referral, confirmatory testing, and early treatment initiation where required.


What does this test measure?

This combined fourth-generation assay detects both antibodies to HIV-1 and HIV-2 and the p24 antigen, a viral protein that appears early in infection. The inclusion of p24 allows detection before antibodies are fully formed.


When is this test recommended?

HIV screening may be recommended following potential exposure, during routine sexual health assessments, before certain medical procedures, or as part of antenatal care. Early testing is particularly important in high-risk situations.


What’s included in this test

Virology
HIV 1&2 Duo with p24 Antigen
