2. Diagnose HIV Infection:
o In individuals with high-risk behavior, symptoms of HIV, or recent exposure to the virus.
3. Protect Pregnancies:

4. Ensure Safe Medical Practices:

Preparation Guidelines:
• No fasting or special preparation is needed for this test.
• A blood sample will be collected from a vein in the arm.
• Inform your doctor about:
o Any recent HIV exposure or symptoms.
o Use of PrEP or PEP (HIV prevention medication), as this can affect the results.
• Be aware that there is a window period (typically 3–8 weeks) after exposure when antibodies may not yet be detectable.
