May aid in the diagnosis of Mycoplasma pneumoniae in patient with persistent pneumonia that is outside of the expected acute phase.
New York DOH Approval Status
Specimen Required
Serum separator tube.
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."
Refrigerated.
Bacterially contaminated, heat-inactivated, hemolyzed, icteric, lipemic, or turbid specimens.
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)

Interpretive Data
Component | Interpretation |
---|---|
Mycoplasma pneumoniae Antibody, IgG | < 0.10 U/L: Negative 0.10-0.32 U/L: Equivocal > 0.32 U/L: Positive |
Mycoplasma pneumoniae Antibody, IgM | 0.76 U/L or less: Negative - No clinically significant amount of M. pneumoniae IgM antibody detected. 0.77-0.95 U/L: Low Positive - M. pneumoniae-specific IgM presumptively detected. Collection of a follow-up sample in one to two weeks is recommended to assure reactivity. 0.96 U/L or greater: Positive - Highly significant amount of M. pneumoniae-specific IgM antibody detected. However, low levels of IgM antibodies may occasionally persist for more than 12 months post-infection. |
