Limitations
IgM antibody testing is valuable for early diagnosis in children; in adults, paired sera for specific IgG and IgM are generally required together with PCR. Specific IgM antibodies are often absent in reinfections; specific IgA might be quite useful in this circumstance.
Clinical Significance
Mycoplasma are the smallest of the free-living organisms. M. pneumoniae causes approximately 10-20% of all cases of pneumonia. These pneumonias that can affect otherwise healthy individuals, are commonly referred to as "walking" and "atypical" pneumonias.
