- After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
|Test Number||Components||Reference Interval|
|0050380||Measles (Rubeola) Antibody, IgG||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).
|0099597||Measles (Rubeola) Antibody, IgM||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.
