Specimen Preparation
Separate serum from cells ASAP or within 2 hours of collection. Transfer 0.5 mL serum to an ARUP Standard Transport Tube. (Min: 0.1 mL) Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens. Mark specimens plainly as "acute" or "convalescent."
Preferred Volume
0.5 mL serum
Minimum Volume
0.1 mL serum
Unacceptable Conditions
Bacterially contaminated, heat-inactivated, hemolyzed, icteric, lipemic, or turbid specimens.
Stability (from collection to initiation)

Storage/Transport Temperature
Refrigerated.
Reference Interval
0.79 AU or less: Negative - No significant level of IgM antibodies to measles (rubeola) virus detected. 0.80-1.20 AU: Equivocal - Repeat testing in 10-14 days may be helpful. 1.21 AU or greater: Positive - IgM antibodies to measles (rubeola) virus detected. Suggestive of current or recent infection or immunization. However, low levels of IgM antibodies may occasionally persist for more than 12 months post-infection or immunization.
