Use

Aid in the diagnosis of atypical pneumonia, which is a cause of community-acquired pneumonia. Primary infection usually occurs in children and reinfection in adults is common. Results must be interpreted in light of each patient's history, physical examination, and other diagnostic findings.

Custom Additional Information

A positive result indicates prior exposure to Mycoplasma. A single positive IgG result may be present in the absence of any clinical symptoms as specific IgG antibodies may remain elevated for up to one year after the initial infection. Recent or acute infection can only be documented by a positive Mycoplasma IgM result and/or a significant increase in the IgG value between sera drawn two to four weeks apart. In some individuals, Mycoplasma IgG levels decline to undetectable levels after four to six months.
