Stability
Room Temperature: 8 hours; Refrigerated: 48 hours; Frozen: 14 days

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 antibodes 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:
<=0.91 Index:   Negative: No antibody detected  
0.91-1.09 Index:   Equivocal: Repeat testing in 10-14 days may be helpful.  
>=1.09 Index:   Positive: IgM antibody to Mycoplasma pneumonia detected, which may indicate acitve or recent infection.
