Understanding the test
What does HIV 1 & 2 Antibodies with P24 Antigen measure?
Also called HIV Ag/Ab Combo (4th Gen)
A clinician may use this combination assay for routine screening or as part of follow-up after possible exposure. Include the exposure date and any prevention medicines when seeking advice.
When it may be requested
Detecting more than one marker
The combination test detects HIV antibodies and p24 antigen, which may appear at different times.
Clarifying a reactive screen
A reactive result follows a confirmatory testing pathway before diagnosis.

SpecimenSerum
Your checklist
No fasting is required. Discuss the exposure date and any HIV prevention medicine with the clinician so the most appropriate test timing can be chosen.
A clinician takes a small sample of blood from a vein. The laboratory uses serum, the liquid separated from the blood after it clots.

Reading your result
A reactive screen requires further testing before a diagnosis. Whether a negative result is conclusive depends on the assay, timing and clinical circumstances.
What can affect it
- A result during the window period may need follow-up appropriate to the exposure and medicines used.

Discuss the next step
Ask which follow-up test and date apply to the particular exposure, especially if the draw was early or you used prevention medicine.

Patient questions
Before you book
Can a negative result immediately after exposure exclude HIV?
No. A laboratory antigen/antibody test using blood from a vein usually detects HIV 18 to 45 days after exposure. If the exposure was within 72 hours, seek urgent assessment for post-exposure prophylaxis (PEP) now, before waiting for a result. Tell the clinician if you took PEP or PrEP, as this can change follow-up testing.
My screening result is reactive: does that mean I have HIV?
No, not on its own. This test is designed to be very sensitive, which means it occasionally reacts to antibodies that have nothing to do with HIV. A reactive result means one thing only: a second, more specific test is needed. Wait for that result before drawing any conclusion, and go through it with your doctor.
Can this HIV test be used for a baby?
Not reliably for a baby born to a parent living with HIV. Antibodies pass from parent to infant and can be present in the baby's blood without the baby being infected, so the test can be reactive for that reason alone. Instead, testing for the virus's genetic material is used to find out whether the baby is infected.
