Reference Range:
Mycoplasma pneumoniae Antibody, IgG <0.10 U/L Negative
0.10-0.32 U/L Equivocal
>0.32 /L Positive
Mycoplasma pneumoniae Antibody, IgM ≤0.76 U/L Negative. No clinically significant amount of M. pneumoniae 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 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.
