HIV Referral Note (Qualitative HIV Antibody Screening)
This test checks for antibodies to the human immunodeficiency virus (HIV), which your body makes in response to infection. It helps determine if you should be tested further for HIV.
["This screening helps identify potential HIV exposure for additional evaluation."]

What This Test Does
The HIV antibody test detects proteins (antibodies) your immune system produces after exposure to HIV. Even if you have early HIV, these antibodies may appear within weeks to months after infection. This test is not used to diagnose HIV directly but to guide further testing if needed.
How the Test Works
Your blood sample is tested using an immunoassay method (often a rapid or enzyme-based test) to detect HIV antibodies. Results are qualitative—meaning they only indicate whether antibodies are present or not.
When You Might Need This Test
Your healthcare provider may recommend this test if you have risk factors for HIV, such as unprotected sex, shared needles, or other behaviors that increase exposure. It may also be part of routine screening in certain settings.
What to Expect Before the Test
No special preparation is needed. You’ll have a small blood sample drawn from your arm, similar to other blood tests. You may feel slight discomfort, but it’s usually over quickly.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions
If antibodies are found, further testing (like a confirmatory HIV test) will be needed to confirm HIV infection. A positive screening result does not mean you have HIV immediately—it may take time for antibodies to develop.
