What is the matter with Mycoplasma pneumoniae antibody IgM positive

A positive IgM antibody for Mycoplasma pneumoniae indicates acute infection with Mycoplasma pneumoniae.

Mycoplasma pneumoniae antibody IgM is an antibody produced by the immune system after mycoplasma infection, and a positive test indicates that there is an existing Mycoplasma pneumoniae infection, which is an indicator of acute infection. Mycoplasma pneumoniae antibody IgM titers above 1:32 are positive.

IgM is usually elevated after 2 weeks of Mycoplasma pneumoniae infection, and because IgM measurements can also be false-positive, the test can be repeated after 2 to 4 weeks, and if the IgM titer is more than fourfold high (1:128), it indicates recent Mycoplasma pneumoniae infection.

Mycoplasma pneumoniae pneumonia presents with fever, shortness of breath, persistent dry cough, may be accompanied by unilateral chest pain, small sputum with blood streaks in sputum, and CT and chest x-ray suggest interstitial changes in the lungs.

The disease is self-limiting, and some patients can recover without treatment, but for those with obvious symptoms, such as cough and sore throat, early active treatment can reduce the symptoms and shorten the course of treatment.

If Mycoplasma pneumoniae antibody IgM is positive, it is recommended to go to the hospital for treatment, improve relevant examinations, and be treated by a professional doctor, so as to avoid self-diagnosis and treatment.
