HIV Antibody Test (Qualitative, Rapid Screening) – Serological HIV IgG Antibody Detection via Rapid Assay

How the Test Works

This test uses a rapid immunoassay (IA) method to detect HIV-specific IgG antibodies in whole blood. A small blood sample is applied to a test strip, where antibodies bind to immobilized viral antigens if present. A visual indicator shows positive or negative results within minutes.

Sample Collection and Preparation

You may collect a blood sample at home using a fingerstick or at a clinic using a needle. The test is designed for self-testing or professional administration. No special preparation is needed, but avoid alcohol or strenuous activity 24 hours before testing.

What to Expect After Testing

Results appear within 15–30 minutes. A positive result means antibodies to HIV are detected, indicating past or current infection. A negative result suggests no detectable antibodies at the time of testing. Follow-up testing (e.g., confirmatory HIV antibody test) is recommended for positive results.

Important Considerations

This test is for screening only and may not detect HIV in the earliest stages of infection (window period). False negatives are possible if tested too soon after exposure. If you’ve had unprotected sex or shared needles recently, consider additional testing or consulting a healthcare provider.
