MYCOPLASMA PNEUMONIAE IgG ANTIBODY

Test Documentation
Specimen Required
Draw blood in a SST. Centrifuge, separate and send 1.0 mL serum (0.5 mL minimum) refrigerated in a screw-capped plastic vial.

Alternate Specimen
Serum: Red-top

Rejection Criteria
Hemolyzed or lipemic specimens

Methodology
Enzyme Immunoassay

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

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.
