Refrigerated.  
Unacceptable Conditions
CSF (refer to Measles (Rubeola) Antibody, IgG, CSF, ARUP test code 0054440). Body fluids, plasma, urine. Contaminated, heat-inactivated, hemolyzed, lipemic or severely icteric specimens.

Stability
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)  
Reference Interval
Effective August 20, 2012

24.9 AU/mL or less: Negative - No significant level of detectable measles (rubeola) IgG antibody.
25.0-29.9 AU/mL: Equivocal - Repeat testing in 10-14 days may be helpful.
30.0 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.
