IgG antibodies to Mycoplasma pneumoniae
IgG antibodies are produced later in the immune response and usually reflect past exposure to Mycoplasma pneumoniae. They tend to appear 2–3 weeks after infection onset and can remain detectable for months or years. A positive IgG result does not necessarily indicate an active infection but shows that the immune system has previously encountered the pathogen. In combination with IgM, IgG testing helps differentiate between acute, recent, and past infections.
