FAQ
What does this test measure? IgG antibodies specific to the measles virus, indicating immunity from vaccination or past infection.
Do I need to fast before this test? No fasting or special preparation is required for this blood test.
How accurate is this test? Modern immunoassays have sensitivity and specificity exceeding 95% (Mayo Clinic 2019).
What if my results are negative? A negative result means you lack immunity and should consult your healthcare provider about vaccination.
Can this test detect active measles infection? No, this IgG test shows immunity status. For active infection, an IgM test is needed.
How long do measles antibodies last? IgG antibodies typically provide lifelong immunity after vaccination or natural infection.
More Details
What is the purpose of this test?
This test determines if you have protective IgG antibodies against measles, indicating immunity from prior infection or vaccination. The test uses validated immunoassay techniques to measure antibody concentration in your blood serum. Over 90% of individuals develop detectable IgG antibodies within 2 weeks of measles infection or vaccination (CDC 2024).
Who would benefit from this test?
Anyone without documented measles immunity should consider this test. This includes healthcare workers, students, international travelers, and pregnant women. With measles cases increasing 300% in 2024 compared to the previous year, largely among unvaccinated individuals (CDC 2024), confirming immunity status is increasingly important for public health protection.
When should I order Rubeola Antibodies Blood Test, IgG?
Order this test before entering school, starting certain jobs, traveling internationally, or if you're unsure of your vaccination status. It's particularly important for healthcare workers, students in healthcare programs, and women of childbearing age. The test is also valuable for preconception planning or prenatal immunity assessment.
How do I interpret the results?
Negative (< 7 IU/mL)
- What it means: No immunity to measles
- Typical action: Consult physician about vaccination
Equivocal (8–9 IU/mL)
- What it means: Uncertain immunity
- Typical action: Repeat testing recommended
Positive (≥ 10 IU/mL)
- What it means: Immune to measles
- Typical action: No further action needed
The measles virus can live for up to two hours in the air, making vaccination crucial for preventing outbreaks.
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 needed for this test. Simply inform the lab if you've had recent vaccinations or symptoms that might affect results. The blood draw requires no special preparation and takes just a few minutes.
How often should I get tested?
- Documented immunity: Suggested interval: Once – lifelong protection expected
- Healthcare worker: Suggested interval: As required by employer
- School/college entry: Suggested interval: As required by institution
- International travel: Suggested interval: Before travel to endemic areas
Why early detection matters
Early confirmation of immunity prevents outbreaks and reduces healthcare costs associated with measles complications. About 20% of measles cases develop complications including ear infection, pneumonia, or more rarely, encephalitis. Knowing your immunity status allows for proactive vaccination and protects both you and your community.
