Positive Mycoplasma pneumoniae refers to the positive antibody of Mycoplasma pneumoniae, suggesting that Mycoplasma infection, if the patient is infected with Mycoplasma pneumoniae, the body will produce corresponding antibodies. 1. Mycoplasma pneumoniae antibodies can be categorized into IgM and IgG antibodies, of which IgM antibodies appear earlier, usually appearing around 1 week after infection, and reaching a peak in 3~4 weeks, so positive IgM antibodies can be used as an indicator of acute infection. 2. IgG is an indicator of previous infection, suggesting previous infection with Mycoplasma, only IgG is positive, and at the same time, no obvious symptoms such as coughing and coughing up sputum do not require treatment. When Mycoplasma pneumoniae antibodies are abnormal, it is recommended to consult a specialist for further clarification.
