Enzyme-Linked Immunosorbent Assay (ELISA)
Same day as tested
Specimen Collection Details
One 7.5 mL serum separator tube (SST). Also acceptable: One 5 mL red top tube.
Allow to clot, centrifuge and separate serum from cells immediately. Refrigerate. Feeze at -20 degrees C if specimen cannot be assayed within 48 hours. Allow no more than one freeze/thaw cycle. If multiple tests are ordered, send separate specimen for this test.
0.5 mL serum.
200 µL serum.
Refrigerated if received in laboratory within 48 hours of collection, or frozen on dry ice.
Gross lipemia; gross hemolysis; heat inactivated or icteric specimen; bacterial contamination; specimen frozen and thawed more than once; refrigerated specimen received in laboratory more than 48 hours after collection.
Rubeola (Measles) IgG Antibody Result Interpretation, ELISA Method:
Negative: No significant level of detectable IgG Rubeola (Measles) antibody, presumed non-immune to measles infection.
Equivocal: Repeat testing in 10-14 days may be helpful.
>= 1.1 IV
Positive: IgG antibody to Rubeola (Measles) detected, which may indicate a current or previous exposure or immunization to Rubeola (Measles). Positive IgG antibody levels in the absence of current clinical symptoms may indicate immunity.
IV = Index Value
The presence of specific antibodies in a single serum specimen indicates past measles infection or vaccination. Demonstration of a significant increase in antibody titers in a serum pair taken at a 14 day interval is the basis for diagnosis of acute infection.
