Understanding your HIV 1/2 Antigen/Antibody Test results
The HIV screening test described here is a fourth-generation antigen/antibody test. It looks for HIV-1 p24 antigen, which appears before antibodies form, and for antibodies to HIV-1 and HIV-2. The result is reported as non-reactive or reactive, with no numeric range. The window period is the time between infection and the point at which a test can detect it. A reactive screening result needs a confirmatory test before any diagnosis is made.
Laboratories word this result in different ways, so the wording on your own report is the one that applies.
How the result is reported
>>>| Result | Finding | Note |
|---|---|---|
| Non-reactive | Not detected | HIV antigen and antibodies were not detected |
| Reactive | Detected on screening | A confirmatory test is needed before any diagnosis |
What a reactive result means
A reactive result means the screening test detected HIV antigen or antibodies. It is not a diagnosis on its own. A second, confirmatory test, such as an HIV-1/2 antibody differentiation test or an HIV RNA test, is done before HIV is diagnosed. HIV is a long-term condition treated with antiretroviral therapy (ART), and treatment can reduce the virus in the blood to an undetectable level.
What a non-reactive result means
A non-reactive result means HIV-1 p24 antigen and HIV-1/2 antibodies were not detected. If the sample was taken during the window period, soon after a possible exposure, the test can miss an early infection, and a repeat test may be advised. The clinic or lab can say what window period applies to the test it uses.
How a doctor reads the result
A doctor or sexual health clinic will interpret an HIV result alongside the timing of any possible exposure and the type of test used. Clinics can also advise on post-exposure prophylaxis (PEP), which is time-sensitive, and on pre-exposure prophylaxis (PrEP). Discuss the result with a doctor.
Follow-up a doctor may arrange
After a reactive screen, the next step is a confirmatory test arranged by the lab or doctor. If HIV is confirmed, care is led by an infectious disease or HIV specialist, who arranges further blood tests and treatment. After a non-reactive result taken during the window period, a doctor may advise a repeat test.
