FAQ
What does this test measure? IgG antibodies to measles, mumps, rubella, and varicella viruses to determine immunity status.
Do I need to prepare for this test? No fasting or special preparation required. Just inform your provider of recent vaccinations.
How accurate is this test? The test has over 95% sensitivity and specificity for confirming immunity (Mayo Clinic 2024).
Can I get vaccinated if I'm not immune? Yes, consult your healthcare provider about vaccination if results show no immunity.
How long does immunity last? MMR and varicella immunity typically lasts for life after vaccination or natural infection.
What if my results are equivocal? Borderline results may require repeat testing or discussion with your healthcare provider.
More Details
What is the purpose of this test?
This panel detects IgG antibodies to measles, mumps, rubella, and varicella viruses to determine if you have immunity from previous vaccination or infection. The test provides serological evidence of protection against these highly contagious diseases that can cause serious complications (CDC 2024).
Who would benefit from this test?
Healthcare workers, students, pregnant women, and travelers benefit most from this testing. Anyone needing documentation for school, employment, or international travel should consider this panel. It's particularly valuable for adults unsure of their vaccination history or those at higher risk of exposure (Mayo Clinic 2024).
When should I order this test?
Order before starting school or new employment, prior to international travel, during preconception planning, or when exposed to these diseases. Testing is recommended if you lack vaccination records or need official immunity documentation (CDC 2024).
How do I interpret the results?
Positive IgG
- What it means: Immune/protected
- Typical action: No vaccination needed
Negative IgG
- What it means: Not immune/susceptible
- Typical action: Consider vaccination
Equivocal IgG
- What it means: Uncertain immunity
- Typical action: Repeat testing or vaccinate
The CDC reports that 90% of unvaccinated individuals exposed to measles will become infected.
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 fasting or medication adjustments are required. Inform your provider of recent vaccinations or illnesses, as these may affect results. The test requires only a standard blood draw at a certified collection site.
How often should I get tested?
- Initial screening: Once if immune
- Immunocompromised: As recommended by physician
- Healthcare workers: Per institutional requirements
- Pregnancy planning: Once before conception
Why early detection matters
Early immunity screening prevents outbreaks and reduces healthcare costs associated with treating these vaccine-preventable diseases. The CDC reported over 1,200 measles cases in 2019—the highest since 1992—highlighting the importance of immunity verification (CDC 2020). Varicella can cause severe complications in adults and pregnant women, making immunity confirmation crucial.
