May aid in the diagnosis of Mycoplasma pneumoniae in patient with persistent pneumonia that is outside of the expected acute phase.
Semi-Quantitative Enzyme-Linked Immunosorbent Assay
New York DOH Approval Status
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."
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)
|0050397||Mycoplasma pneumoniae Antibody, IgG||< 0.10 U/L: Negative
0.10-0.32 U/L: Equivocal
> 0.32 U/L: Positive
|0050398||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.
