This immunity panel measures IgG antibodies for measles, mumps, and rubella to determine if you are immune — either from prior vaccination or natural infection. Many adults lack proof of vaccination or may have waning immunity. This test is commonly required for healthcare workers, college enrollment, international travel, and anyone who wants to verify their protection status.
Immunity testing confirms protective antibody levels from past infection or vaccination — useful for travel, occupational, prenatal, or post-illness verification.
Healthcare workers, travelers, pregnant individuals or those planning pregnancy, immunocompromised patients, and anyone confirming vaccine response or natural immunity.

3 biomarkers tested
Your MMR Immunity Test (Measles, Mumps, Rubella) results will include values for each of the 3 biomarkers tested, along with reference ranges. Results are reviewed by a licensed physician before being released to your secure portal.
If any values fall outside the normal range, your report will include guidance on what that may mean and recommended next steps. You'll receive an email notification when your results are ready, typically within 3–5 business days.
Typical reference range layout
Lab reports show where your value sits relative to established reference intervals—your physician interprets this in context for you.
No fasting required.
The short answer
Worth it when an institution demands proof of MMR immunity and your vaccination records are lost, abroad, or not accepted - the titer IS the proof, no records needed. If your form accepts a new vaccination card instead, price both routes first: an MMR booster at a pharmacy can cost less than the titer.
We would rather you order the right test than the most expensive one.
A standard walk-in venous draw at Quest - no fasting, no preparation. All three antibodies (measles, mumps, rubella) come from the same tube, and if you also need varicella or hepatitis B titers or a TB test, everything can be drawn in the same visit (see the [Pre-Enrollment Health Panel](/tests/pre-enrollment-health-panel)).
An at-home draw is not recommended for this test — it needs a lab-based collection to be accurate.
The markers that matter most and what an out-of-range value can mean. Reference ranges vary by lab, age and sex.
| Marker | Typical range | What it means |
|---|---|---|
| Measles (rubeola) IgG | Positive / immune | Positive documents protection. Non-immune means one MMR booster - measles immunity is the component institutions scrutinize hardest during outbreaks. |
| Mumps IgG | Positive / immune | Mumps antibodies wane most often of the three; an isolated non-immune mumps result is common and is fixed with a single booster. |
| Rubella IgG | Positive / immune | Rubella immunity matters especially for anyone who may become pregnant and for healthcare settings; non-immune means one booster (not given during pregnancy). |

A MMR Immunity Test (Measles, Mumps, Rubella) test costs $289.99 at TestWell — $295.99 all-in when ordered alone, because the $6 lab processing fee is charged once per order, with no draw fee or physician fee added.
