What is an HIV 1 & 2 Antibody Test?
The HIV 1 & 2 Antibody test is a fundamental screening tool used to detect the presence of antibodies produced by the immune system in response to the Human Immunodeficiency Virus. This test specifically screens for both major strains of the virus: HIV-1, which is the most common strain worldwide, and HIV-2, which is more prevalent in specific regions including parts of India. An HIV test in Kolkata is a vital step for early diagnosis, allowing for timely medical intervention and the prevention of further transmission.
The Clinical Difference Between HIV-1 and HIV-2
Understanding which strain is present is critical because they differ in progression and treatment response:
- Viral Progression: HIV-2 generally progresses to stage 3 HIV (AIDS) more slowly than HIV-1 and typically results in a lower viral load in the blood.
- Treatment Resistance: HIV-2 is naturally resistant to certain classes of antiretroviral drugs (like NNRTIs) that are commonly used to treat HIV-1.
- Detection: Because the two strains are genetically distinct, a test must be specifically designed to detect the unique antibodies of both types.
- Confidential Screening: This test serves as an essential initial screen; a reactive result is always followed by a confirmatory differentiation assay to identify the specific strain.

It is important to be aware of the "window period"—the time it takes for the body to produce enough antibodies to be detected. For most people, this is between 23 to 90 days after exposure. If you have had a recent high-risk exposure, a follow-up test after the window period is recommended.
