About this test
What is the HIV 1 & 2 Antibodies, Screening Test?
The test detects antibodies produced by the immune system in response to HIV‑1 and HIV‑2 viruses. It is a screening test used to identify people who may have been infected with HIV.
Key Parameters
| Parameter | What it shows |
|---|---|
| HIV‑1 antibodies | Presence of immune response to HIV‑1 |
| HIV‑2 antibodies | Presence of immune response to HIV‑2 |
Why is this test done?
- Routine screening for people at risk of HIV infection.
- Evaluation of symptoms such as fever, weight loss, or unexplained lymphadenopathy.
- Monitoring of patients on antiretroviral therapy to confirm seroconversion.
Early Detection
The test can help identify signs of HIV infection, but it does not diagnose the disease on its own. A doctor interprets the result together with symptoms, medical history, and confirmatory tests.
What an abnormal result may mean
A positive result indicates that antibodies to HIV have been detected. Many factors such as recent vaccination, other infections, or laboratory error can affect results, so confirmatory testing is required.
Who might be advised to get this test?
- Individuals with potential exposure to HIV (unprotected sex, needle sharing, etc.).
- Pregnant women to prevent mother‑to‑child transmission.
- Healthcare workers and others with occupational risk.
Summary
This screening test checks for HIV antibodies in blood. A positive result requires confirmatory testing and clinical evaluation.
