Aid in the diagnosis of measles infection. Test may not be helpful in patients who have recently received an MMR vaccination.
Semi-Quantitative Enzyme-Linked Immunosorbent Assay/Semi-Quantitative Chemiluminescent Immunoassay
Mon, Wed, Fri
New York DOH Approval Status
Serum separator tube.
Separate serum from cells ASAP or within 2 hours of collection. Transfer 1 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."
Refer to individual components.
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
|Measles, Rubeola, Antibody IgM||0.79 AU or less|
|Measles (Rubeola) Antibody, IgG||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).
|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.
