HIV DUO Test in Colorado

Quick answer
The HIV 4th Generation Antigen/Antibody Test, often called the DUO test, looks for both HIV antibodies and the p24 antigen in a blood sample. Earlier generation tests detected only antibodies, which take weeks to develop. Adding the antigen marker allows the test to detect infection sooner after exposure, though a window period still applies.
What this test measures
When HIV enters the body, the p24 antigen appears in the blood before antibodies form. A fourth generation test measures both, so it can detect infection earlier than antibody-only tests. This combined approach has become the standard initial screen for HIV in many laboratories.
The sample is blood drawn from a vein. If the combined screen is reactive, a follow-up test is performed to confirm the result and to distinguish HIV-1 from HIV-2 where relevant. Screening tests are designed to be sensitive, so a reactive screen is not final until confirmatory testing is complete.
No test can detect infection immediately after exposure, because the virus and the immune response both take time to become measurable. A healthcare provider can advise on when to test and whether repeat testing is appropriate. Results are confidential and should be discussed with a qualified provider.
