After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
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."
Storage/Transport Temperature
Refrigerated.

Performed
Mon-Fri
Unacceptable Conditions
Bacterially contaminated, heat-inactivated, hemolyzed, icteric, lipemic, or turbid specimens.
Ordering Recommendations
Aid in the diagnosis of acute measles infection. Consider ordering Measles (Rubeola) Antibodies, IgG and IgM (0050375).
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.
