FAQ
What diseases does this panel test for? This panel measures antibodies for Hepatitis A, Hepatitis B, Measles, Mumps, Rubella (MMR), and Varicella (chickenpox).
Do I need to fast before this test? No fasting is required. Avoid biotin supplements for at least 8 hours before testing as they may interfere with results.
How soon after vaccination should I test? Wait at least 6–8 weeks post-vaccination for the most accurate antibody results (CDC 2024).
What if my results show I'm not immune? Non-immune results may indicate you need vaccination or booster shots. Consult your healthcare provider for appropriate follow-up.
Can this test detect active infections? This test measures antibodies indicating past infection or vaccination, not active infections. It cannot distinguish between current and past infections.
Are my results confidential? Yes, all results are confidential and accessible only through your secure online account with optional physician review available.
More Details
What is the purpose of this test?
The Immunity Plus Blood Test Panel determines whether you have protective antibodies against six common infectious diseases: Hepatitis A, Hepatitis B, Measles, Mumps, Rubella, and Varicella (chickenpox). By measuring IgG and total antibodies in your blood, this comprehensive panel confirms immunity developed through previous infection or vaccination (Mayo Clinic 2024).
The test is particularly valuable for verifying immunity status when documentation is required for employment, school enrollment, travel, or prenatal care. Healthcare workers, students, and pregnant women frequently use this panel to meet compliance requirements and ensure protection against these preventable diseases.
Who would benefit from this test?
This test is ideal for individuals who need documented proof of immunity for professional, educational, or personal reasons. Healthcare workers and students entering medical programs often require immunity verification as part of their training requirements (CDC 2024).
Pregnant women benefit from knowing their immunity status, as some infections can cause serious complications during pregnancy. International travelers visiting areas where these diseases are endemic should verify immunity before departure. Adults with unclear vaccination histories can use this test to identify gaps in their protection.
When should I order Immunity Plus Blood Test Panel?
Order this test when you need documentation for work, school, or travel requirements. If you're pregnant or planning pregnancy, testing early helps ensure protection against infections that could affect your baby (American Academy of Pediatrics 2024).
Consider testing if you're uncertain about your vaccination history or if you work in high-risk environments like healthcare or education. If you've recently been vaccinated, wait 6–8 weeks for accurate antibody development before testing.
How do I interpret the results?
Results are reported as either immune (positive/adequate antibody levels) or non-immune (negative/low antibody levels) for each disease tested. Some results are quantitative (numeric values) while others are qualitative (positive/negative indicators).
Result: Immune / Positive
- What it means: Protective antibodies present
- Typical action: No action needed; immunity confirmed
Result: Non-immune / Negative
- What it means: Low or absent antibodies
- Typical action: Consider vaccination or booster
Result: Borderline / Equivocal
- What it means: Uncertain immunity status
- Typical action: Discuss with healthcare provider
The sensitivity of IgG-based measles and rubella antibody tests exceeds 95%, making them highly reliable for immunity verification (CDC 2024).
Disclaimer: Reference ranges may vary by laboratory. Listed ranges are general guidelines and may differ from those used by the performing lab. Always consult your healthcare provider for interpretation.
Pre-test preparation
No special preparation is needed for this test. You don't need to fast or avoid normal activities. However, avoid biotin supplements for at least 8 hours before testing, as they may interfere with certain assay methods (Johns Hopkins Medicine 2023).
If you've recently received vaccinations, wait 6–8 weeks before testing to allow adequate time for antibody development. Bring a valid photo ID to your lab appointment.
How often should I get tested?
Testing frequency depends on your circumstances and risk factors. Most people need testing only when required for specific purposes or when immunity status is uncertain.
- Employment/school requirement: Suggested interval: One-time or as mandated
- Pregnancy planning: Suggested interval: Before each pregnancy
- Healthcare worker: Suggested interval: Per employer policy
- Immunocompromised: Suggested interval: As recommended by physician
- Post-vaccination verification: Suggested interval: 6–8 weeks after immunization
Why early detection matters
Knowing your immunity status prevents serious complications from preventable diseases. Early identification of immunity gaps in healthcare workers reduces workplace outbreaks by up to 70% (CDC 2023).
Economic modeling shows that verifying immunity before employment or travel saves an average of $300–$500 per individual in avoided disease costs and productivity loss (Johns Hopkins Medicine 2023). Pregnant women who know their immunity status can take appropriate precautions to protect their developing baby.
