Allow specimen to clot completely at room temperature. Separate from cells ASAP or within 2 hours of collection. Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.5 mL) Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens.
Unacceptable Conditions
Contaminated, heat-inactivated, grossly hemolyzed, lipemic or severely icteric specimens.
Storage/Transport Temperature
Refrigerated.
Stability (from collection to initiation)
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (Avoid repeated freeze/thaw cycles)
Performed
Sun-Sat
Remarks
Label specimens plainly as acute or convalescent.
Notes
For CSF, refer to Measles (Rubeola) Antibody, IgG, CSF (ARUP test code 0054440).
Not recommended as a stand-alone test unless testing for evidence of antibody production from vaccination. For cerebrospinal fluid, order Measles (Rubeola) Antibody, IgG, CSF (0054440).
Performed
Sun-Sat
Methodology
Semi-Quantitative Chemiluminescent Immunoassay
Reported
Within 24 hours
Synonyms
Rubeola Ab, IgG
Rubeola Antibodies Screen, IgG
Rubeola Antibodies, IgG
Rubeola serology
ARUP Test Code
0050380
Reference Interval
Effective September 3, 2019
13.4 AU/mL or less: Negative - No significant level of detectable measles (rubeola) IgG antibody. 13.5-16.4 AU/mL: Equivocal - Repeat testing in 10-14 days may be helpful. 16.5 AU/mL or greater: Positive - IgG antibody to measles (rubeola) detected, which may indicate a current or past exposure/immunization to measles (rubeola).
Interpretive Data
The best evidence for current infection is a significant change on two appropriately timed specimens, where both tests are done in the same laboratory at the same time.
