What This Test Checks For

HIV-1 and HIV-2 Antibodies

This test checks for antibodies that the immune system may make after exposure to HIV.

• Test name: HIV Antibody, HIV 1/2, EIA with Reflexes
• Also known as: HIV 1/2 Antibody Test, HIV Screening Test, HIV EIA
• Sample type: Blood
• Purpose: HIV screening
• Insurance: Not required

Who May Need This Test?

• Individuals completing routine HIV screening
• Students completing school or clinical program requirements
• Healthcare workers or employees completing onboarding requirements
• People with possible HIV exposure
• Individuals with a new sexual partner or multiple partners
• Anyone whose healthcare provider requested HIV testing

Important: HIV Exposure and PEP

If you think you may have been exposed to HIV within the last 72 hours, seek urgent medical care immediately to discuss HIV post-exposure prophylaxis, PEP.

Do not wait for online lab testing if you may need PEP. PEP is time-sensitive and works best when started as soon as possible.

Window Period: When HIV Can Be Detected

HIV tests have a window period, which is the time between exposure and when a test can reliably detect infection.

• Antibody-only tests may take longer to become positive after exposure.
• 4th generation HIV antigen/antibody tests can usually detect HIV earlier than antibody-only tests.
• HIV RNA testing may be used in some situations when very recent exposure or acute infection is suspected.

If your exposure was recent, a negative result may need repeat testing later. Ask a healthcare provider which test and timing are right for your situation.

HIV Antibody Test vs 4th Generation HIV Test

This product is listed as an HIV antibody test with reflexes. Some schools, employers, or healthcare providers may request a 4th generation HIV antigen/antibody test instead.

Before ordering, confirm whether your form or provider requires:

• HIV 1/2 antibody test
• HIV 4th generation antigen/antibody test
• HIV RNA test
• HIV test with reflex confirmation

Understanding Your Results

Negative or Nonreactive

A negative or nonreactive result means HIV antibodies were not detected in the sample tested.

If exposure was recent, repeat testing may be needed because antibodies can take time to develop.

Positive or Reactive

A positive or reactive screening result requires confirmatory testing and follow-up with a licensed healthcare provider.

If your result is reactive, do not assume the final interpretation until all reflex or confirmatory testing is complete.

Important Symptom Warning

If you have fever, rash, sore throat, swollen lymph nodes, flu-like illness after possible exposure, recent high-risk exposure, or any urgent health concern, contact a healthcare provider promptly.

If exposure occurred within 72 hours, seek urgent care immediately to discuss PEP.

Important: Testing Only, Not Treatment

LabReqs and SchoolTiters provide access to lab testing. We do not diagnose HIV, provide HIV treatment, prescribe PEP or PrEP, provide partner notification, or replace care from a licensed healthcare provider.

If your result is reactive or if you have recent exposure concerns, follow up with a healthcare provider, urgent care, health department, or HIV/STI clinic.

Important Limitations

• This test may not detect very recent HIV exposure during the window period.
• If your exposure was recent, repeat testing may be needed.
• This product may not be the same as a 4th generation HIV antigen/antibody test.
• This test does not include HIV RNA testing unless specifically included or ordered separately.
• This test does not provide treatment or prevention medication.
• Reactive screening results require confirmatory testing and medical follow-up.

Before Ordering

• Confirm whether your requirement asks for HIV antibody, HIV 4th generation, or HIV RNA testing.
• If you had possible exposure within 72 hours, seek urgent medical care for PEP evaluation before ordering.
• If exposure was recent, ask a healthcare provider about the correct test and timing.
• If you need other STI testing, such as syphilis, chlamydia, gonorrhea, or hepatitis testing, those must be ordered separately unless included in a panel.
