Geisinger Epic Procedure Code: LAB3026 Geisinger Epic ID: 7469Serum
0.5 mL serum; minimum 0.2 mL.
Allow to clot. Centrifuge and submit 0.5 mL serum.
Refrigerated (preferred). Room temperature (stable 8 hours) and frozen specimens also acceptable.
Room temperature: 8 hours. 2-8°C: 7 days. Frozen: 6 months.
Specimen stability exceeded; specimen grossly hemolyzed.
| Result | Interpretation |
| Negative | Absence of detectable measles virus IgG antibodies. A negative result generally indicates that the patient has not been infected and is susceptible to measles. If the subject has no history of measles, has not been previously vaccinated and exposure to measles virus is suspected despite a negative finding, a second sample should be collected no less than 1-2 weeks later. |
| Equivocal | Equivocal samples should be retested. If the result remains equivocal after repeat testing, a second sample should be recollected no less than 1-2 weeks later. |
| Positive | Presence of detectable measles virus IgG antibodies. A positive result generally indicates past exposure to measles virus or previous vaccination. |

Qualitative determination of IgG antibodies to measles.

Measles (rubeola) is a highly contagious disease resulting from infection by rubeola virus. Serology tseting for measles can ascertain the immune status of previously vaccinated individuals and detect seroconverstion in recently vaccinated individuals. A positive rubeola IgG antibody in the absence of a current or recent infection is evidence of immunity to rubeola. Acute infection is diagnosed by testing for rubeola IgM antibody.
