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).
Semi-Quantitative Chemiluminescent Immunoassay
Within 24 hours
Serum Separator Tube (SST).
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.
Contaminated, heat-inactivated, grossly hemolyzed, lipemic or severely icteric specimens.
Label specimens plainly as acute or convalescent.
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (Avoid repeated freeze/thaw cycles)
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).
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.
For CSF, refer to Measles (Rubeola) Antibody, IgG, CSF (ARUP test code 0054440).
