Mycoplasma pneumoniae Antibodies, IgM
Also known as: Atypical Pneumonia Antibodies, Pleuropneumonia-like Organism (PPLO) Antibodies
Use
Aid in the diagnosis of atypical pneumonia and Stevens-Johnson syndrome by providing laboratory support for a Mycoplasma pneumoniae infection. Results must be interpreted in light of each patient's history, physical examination, and other diagnostic findings.
Special Instructions
Low positive results (770-950 units/mL) are presumptive evidence of acute or recent infection. It is recommended that the test be repeated on a fresh specimen one to two weeks later to assure reactivity. Specific IgM may persist for several months after initial infection or be absent during reinfection.
Limitations
The absorbent used in this assay removes as much as 15 mg/mL of human IgG, but the presence of residual IgG in individuals with hypergammaglobulinemia may affect results adversely.
