IgG antibodies to Mycoplasma pneumoniae
IgG antibodies are produced later in the immune response and usually indicate past exposure to Mycoplasma pneumoniae. They generally appear 2–3 weeks after the onset of infection and can remain detectable for months or even years. A positive IgG result does not necessarily mean there is an active infection but shows that the immune system has previously encountered the pathogen. When used alongside IgM testing, IgG helps distinguish between active, recent, and past infections.
