Mycoplasma pneumoniae antibodies include IgM and IgG antibodies, of which IgM is an important indicator to confirm the diagnosis of acute mycoplasma infection, with a normal reference value within 1:32, while a positive IgG for Mycoplasma pneumoniae indicates that the patient may have been infected with mycoplasma in the past, but it cannot be used as a basis for clinical diagnosis of mycoplasma infection. When there is a positive IgM antibody, it is possible to determine that the patient is infected with Mycoplasma pneumoniae. Treatment should be made in conjunction with the clinical features of the patient. If there are more obvious respiratory symptoms such as cough and sputum, and the lung imaging suggests inflammatory changes, actively select drugs for mycoplasma infection to control the infection, which are commonly used clinically, such as azithromycin and moxifloxacin.
