Reference Interval:
 
Test Number Components Reference Interval
0050397Mycoplasma pneumoniae Antibody, IgG < 0.10 U/L: Negative
0.10-0.32 U/L: Equivocal
> 0.32 U/L: Positive
0050398Mycoplasma 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.
