Reference Range

≤0.90 Seronegative: Suggests no prior immunological exposure to Mycoplasma pneumoniae, result does not rule out recent exposure and collection of test sample prior to development of IgG. IgM anti-Mycoplasma pneumoniae and/or culture is recommended for determining current infection.
0.91 - 1.09 Equivocal: Immunological exposure cannot be assessed with this value. Recommend repeat testing in 7 - 14 days. If repeat testing remains equivocal an alternative method should be used. A test for IgM anti-Mycoplasma pneumoniae antibodies may be helpful in acute infections.
≥1.10 Seropositive: Indicates presence of IgG antibody to Mycoplasma pneumoniae. IgM anti-Mycoplasma pneumoniae level may be useful if a recent infection is suspected clinically.
