IgM antibodies to Mycoplasma pneumoniae
IgM antibodies are the first type of antibodies produced by the immune system in response to an acute infection. When IgM against Mycoplasma pneumoniae is present, it typically indicates a recent or ongoing infection. These antibodies appear within 1–2 weeks of exposure and usually decline after a few months. Testing for IgM is useful in identifying the early phase of a Mycoplasma pneumoniae infection, especially in symptomatic individuals.
