Sample

Blood draw or sample collection at a local center

A measles immunity test checks for IgG antibodies against the measles virus, also called rubeola. It helps determine whether a person is likely protected through vaccination or a past infection. People often order it to document immunity for school, work, or travel, or because their vaccination history is uncertain. The test uses a blood sample and reports the antibody level. A healthcare provider interprets the result with your history to judge whether it suggests protection or whether vaccination may be considered.

• Measles (rubeola) IgG antibody Antibodies that generally indicate immunity to measles from vaccination or past infection.

• People who need documented proof of measles immunity
• Individuals unsure whether they were vaccinated against measles
• Healthcare, school, or childcare workers with immunity requirements
• People with a possible recent exposure to measles
• Individuals whose healthcare provider wants to confirm measles status

• No fasting is required for this blood test
• A standard blood draw is used to collect the sample
• Bring any vaccination records you have
• Tell the lab if you have a recent possible exposure or rash illness

A positive or detectable measles IgG level generally suggests immunity, while a negative or low level may mean protection is uncertain. The result is interpreted alongside vaccination history and any possible exposure. A low titer does not necessarily mean a person is unprotected, and a healthcare provider can help decide whether additional vaccination is appropriate. Discuss your measles IgG result with a healthcare provider before making any decisions.
