Reference Range

Mycoplasma IgG:
≤0.90 Seronegative: Suggest 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.

Mycoplasma IgM:
≤0.90 Index: Negative: No antibody detected
0.91 - 1.09 Index:|Equivocal: Repeat testing in
10 - 14 days may be helpful.
≥1.10 Index: Positive: IgM antibody to
Mycoplasma pneumonia detected, which
may indicate acitve or recent infection.
