Mycoplasma pneumoniae antibodies are used to detect whether a patient is infected with mycoplasma pneumonia caused by mycoplasma. The diagnosis of mycoplasma pneumonia is confirmed if the serum mycoplasma IgM antibody is ≥1:64 or if there is a 4-fold increase in antibody titer during the recovery period. The diagnosis can also be confirmed by a condensation set test, if the condensation set test is positive and the titer is ≥1:32, the diagnosis of mycoplasma pneumonia can also be confirmed. Mycoplasma pneumonia mainly manifests as cough, sputum, general malaise, fever, headache, and is treated clinically with macrolide antibacterial drugs, such as azithromycin and roxithromycin, for a period of 2-3 weeks.
