Mycoplasma pneumoniae Antibodies,IgM, Serum

See Also Mycoplasma pneumoniae Antibodies, IgG, Serum

Elevation of M. pneumoniae-specific IgM alone can often be interpreted as evidence of acute infection, since this antibody typically appears within 1 week of the initial infection and approximately 2 weeks before IgG antibody. However, the presence of IgM is considered most significant in paediatric populations, where there have been fewer opportunities for repeated exposures. In adults, re-infection leads directly to an IgG response; therefore, the absence of a positive IgM test does rule out an acute infection.
