Measles (Rubeola) Antibodies, IgG
Also known as: Measles
Use
This test is used to aid in the determination of serological status to measles virus. A positive result generally indicates exposure to measles virus or previous vaccination. A positive result is considered adequate laboratory evidence of measles immunity. Persons with an equivocal serologic test result do not have adequate presumptive evidence of immunity and should be considered sesceptible unless they have other evidence of measles immunity.
Special Instructions
Identify specimen as acute or convalescent. Acute and convalescent specimens must be submitted on separate request forms.
Limitations
Equivocal results should be considered negative for immunity purposes and indicate susceptibility without further evidence. Documented vaccination supersedes serologic testing outcomes, and negative or equivocal results in vaccinated individuals should not prompt additional vaccine doses. Test performance may vary based on sample handling, such as hemolysis or bacterial contamination, which could lead to specimen rejection.
