Mycoplasma pneumoniae is negative, which means that there is no infection by the mycoplasma. The normal ratio of Mycoplasma pneumoniae is 1:20, more than 1:20 is positive, and the clinically significant value is more than 1:80. When the patient’s mycoplasma antibody appears to be more than 1:80, it is necessary to further distinguish between the IgM positive, or the IgG positive, and to combine with the clinical symptoms. If the patient does not have any clinical symptoms and the IgG antibody is positive, it is considered that the patient may have been infected with mycoplasma in the past, and there is no need for medication at this time. If the patient has recently developed symptoms such as cough, fever, headache, depression, nausea, etc., and the IgM antibody is positive, it is considered that the patient has recently developed mycoplasma infections, and anti-mycoplasma treatment is needed, and the commonly used drugs include macrolide antibiotics and quinolone antibiotics.
