The general test for Mycoplasma pneumoniae antibodies costs up to$100. It can be categorized into IgM antibody and IgM antibody. This is because the incubation period of Mycoplasma pneumoniae infection is 2-3 weeks. By the time a patient presents with symptoms and seeks medical attention, the IgM antibodies in the body have already reached a fairly high level, so positive IgM antibodies can be used as a diagnostic indicator of the acute phase of the infection. If the IgM antibody is negative, it does not negate the Mycoplasma pneumoniae infection, and it is also necessary to test the IgG antibody, which appears later than the IgM and needs to be observed dynamically. In general, most mycoplasma infections are self-limiting and can improve in about two weeks without special treatment. Unless the symptoms are more serious, symptomatic and anti-Mycoplasma pneumoniae treatment can be carried out to shorten the course of the disease.
