• HIV-1 Antibody: This parameter detects antibodies against HIV-1, the strain responsible for the majority of global HIV infections. If the immune system has encountered this virus, specific proteins (antibodies) will be present in the serum.
• HIV-2 Antibody: This parameter detects antibodies against HIV-2. While less common and generally less virulent than HIV-1, it can still lead to immunodeficiency. Because the two strains are genetically distinct, the ELISA is designed to detect unique antibodies for both.

What is the "window period"?

This is the time between potential exposure and when the test can accurately detect antibodies. For ELISA, this is typically 3 to 12 weeks.

Does a "Reactive" result mean I definitely have AIDS?

No. Reactive means HIV antibodies were detected. AIDS is the advanced stage of HIV infection, which can be prevented with modern treatment.

How accurate is the HIV ELISA test?

It is extremely accurate (over 99% sensitive), but because it is so sensitive, false positives can occur, which is why confirmatory testing is mandatory.

Can I get HIV from the blood draw?

No. Labs use sterile, single-use needles for every patient. There is zero risk of contracting HIV from taking the test.

What if I tested "Non-Reactive" but I had exposure yesterday?

The test will likely be negative because antibodies haven't formed yet. You must repeat the test after the window period (6–12 weeks).

Does this test detect the virus itself?

No, it detects the antibodies your body makes against the virus. A PCR test is required to detect the virus directly.

Is the test result confidential?

Yes, HIV results are protected by strict medical confidentiality laws and are only shared with the patient and required health authorities.

Can a cold or flu cause a false positive?

It is rare, but certain viral infections or autoimmune conditions can occasionally cause a "cross-reactive" false positive.

What is the difference between HIV-1 and HIV-2?

HIV-1 is the most common globally. HIV-2 is less common, less infectious, and progresses more slowly to illness.

Can I take the test during my period?

Yes, menstrual cycles do not affect the presence of HIV antibodies in the blood.

Do I need to fast before the test?

No, food or drink intake does not alter the antibody levels in your serum.

How soon can I get my results?

At Dr. Patho Labs & Diagnostics, the report is typically available within 4–6 hours.

Can I get tested anonymously?

Many centers offer anonymous testing where a code is used instead of your name. Check with your local facility.

What should I do if my result is Reactive?

Stay calm and speak with a healthcare professional immediately. They will order a confirmatory test and provide guidance on next steps.

If the confirmatory test is positive, is there a cure?

While there is no cure, highly effective Antiretroviral Therapy (ART) allows people with HIV to live long, healthy lives and prevents transmission to others.
