HIV 1 & 2 Antibodies Test

Human immunodeficiency virus (HIV) is a virus that weakens the body’s immune system by attacking the cells that help the body fight infections. The virus has two main subtypes (HIV-1 and HIV-2) based on differences in their genes and the proteins on their surface.

HIV spreads through contact with infected body fluids, most commonly through unprotected sex or sharing needles. Over time, if not managed, HIV can progress to acquired immunodeficiency syndrome (AIDS), which is the most advanced stage of infection where the immune system becomes severely damaged. Since HIV may not cause noticeable symptoms in the early stages, testing is the only reliable way to know your status.

This HIV test is done to detect the presence of HIV-1 and HIV-2 by checking antibodies (proteins made by the immune system to recognise and fight harmful substances) in the blood. If you think you are exposed to this infection or your doctor believes you have been at risk, this screening test is important for you. It is simple, quick, and a reliable indicator for early risk assessment.

You may consider taking this test if you belong to any of the following categories:

• Anyone who has had unprotected vaginal, anal, or oral sex
• Individuals with multiple sexual partners or a new partner
• People who share needles, syringes, or drug injection equipment
• If you have been diagnosed with other sexually transmitted infections (STIs) such as syphilis, gonorrhoea, or chlamydia
• Pregnant women or those planning pregnancy (to prevent transmission to the baby)
• Anyone whose partner is HIV-positive or whose status is unknown
• Individuals with symptoms suggestive of early HIV infection, such as fever, headache, sore throat, rash, fatigue, weight loss, diarrhoea, or swollen glands.

Important: HIV may not show symptoms for years, so testing is essential (if you or your doctor thinks you might be at risk) even if you feel healthy.

The frequency of HIV 1 & 2 Antibodies test depends on your risk factors, lifestyle, and any recent exposure:

An HIV 1 & 2 Antibody test looks for antibodies produced by the body in response to HIV infection in the blood. This test helps to assess the risk of:

• HIV 1 infection
• HIV 2 infection

Note: HIV antibody test is primarily used as a screening test, not a confirmatory test.

What to Expect Before the HIV 1 & 2 Antibodies Test

No fasting is required for a standalone HIV 1 & 2 Antibodies test. You can eat and drink normally. However, if it is part of a broader package that includes fasting tests, your doctor may advise fasting for 8-12 hours. Avoid strenuous exercise for 24 hours before the test, as intense physical activity can temporarily raise HIV 1 & 2 Antibodies levels and affect interpretation. Always inform your doctor about any ongoing medications.

What to Expect During the Blood Collection

A phlebotomist cleans the skin with an antiseptic, then places an elastic band around your upper arm to make the veins easier to access. A small needle is inserted into the vein; you may feel a brief pinch. Blood is collected into a labelled tube in under a minute.

What to Expect After the HIV 1 & 2 Antibodies Test

A small cotton swab and bandage are placed over the site to stop any minor bleeding. You can return to normal activities immediately. Minor bruising is normal and disappears quickly. If dizzy, sit and rest for a few minutes.

The HIV 1 & 2 Antibodies test consists of the following parameters:

• HIV 1 and 2 Antibodies: Presence of antibodies against HIV 1 and HIV 2

The results of an HIV 1 & 2 Antibodies test are reported qualitatively (not as numerical values):

Important:

• Results may vary depending on lab methods.
• Results should always be interpreted by a qualified doctor along with symptoms and medical history.
• For the HIV test price, please contact your local diagnostic centre or check online on our website/app.

Understanding your HIV blood test result is important, as this screening test only indicates whether HIV antibodies are present and may require further confirmation for a final diagnosis.

Note:

• A non-reactive (negative) result is considered normal. However, if the test is done too soon after exposure (before 4 to 12 weeks of exposure), results may fall within the window period (the period where antibodies against the virus are not high enough to be detected by the test), and repeat testing may be needed (after 4 to 12 weeks).
• Any reactive (positive) result should be confirmed with additional specific tests.

The HIV test procedure involves a simple blood sample and carries minimal risk, such as slight pain or bruising at the needle site, which, if it occurs, resolves quickly on its own.

While the HIV 1 & 2 Antibodies test is safe and widely used for screening, it has certain limitations to consider:

• The test may not detect HIV if done too soon after exposure, leading to a false-negative result.
• In rare cases, the test may show a positive result even without infection.
• A reactive (positive) result requires additional confirmatory tests for diagnosis.
• The test only detects antibodies and cannot determine the severity or progression of HIV.

If your HIV antibody test result is reactive or if there is a high suspicion of infection, additional tests may be recommended for confirmation and further evaluation. These include:

• HIV viral load test
• p24 antigen test/4th generation HIV test
• Complete blood count (CBC)
