Two tests for Mycoplasma pneumoniae
The two tests for Mycoplasma pneumoniae generally refer to the Mycoplasma pneumoniae IgM and IgG tests.
A simple positive IgM indicates that the patient has a recent Mycoplasma pneumoniae infection, and the serum IgG antibody titer during the convalescent period increases more than 4-fold or decreases, which also indicates that the patient has a recent infection. It appears later than IgGIgM and requires dynamic observation. If markedly elevated, indicates acute infection; If it is significantly reduced, it indicates advanced infection; If there are no changes, the patient may have been infected in the past. Mycoplasma pneumoniae can be transmitted through droplets and direct contact. Symptoms usually begin 1-3 weeks after exposure to the pathogen.
Clinically, it can be manifested as fatigue, muscle aches, severe dry cough, sore throat, chest pain, headache, etc. Some people also have a fever, usually a moderate fever. A positive culture for Mycoplasma pneumoniae is the gold standard for diagnosis. Mycoplasma pneumoniae includes IgM antibodies and lgG antibodies, with IgM antibodies reflecting the diagnostic markers of recent acute infection. LgG antibodies reflect the diagnostic markers of previous mycoplasma infection. The incubation period for Mycoplasma pneumoniae infection is 2-3 weeks, so when a patient is diagnosed with Mycoplasma pneumoniae infection, develops a high fever, has a temperature of more than 39 degrees Celsius, and has a dry cough, the level of lgM antibodies reaches very high. When IgG antibodies are positive, no special treatment is required, only regular follow-up tests are required. When IgM antibodies are positive, antimycoplasma drugs such as azithromycin, erythromycin, levofloxacin, moxifloxacin, etc., should be used.
Mycoplasma pneumonia is mainly an infectious disease caused by infection with mycoplasma in the lungs. Mycoplasma pneumonia is a disease that usually has a slow onset and is more harmful to the human body. In the early stages, some patients often have less obvious symptoms and only have a fever or mild cough, making it generally difficult to diagnose in the early stages. Therefore, mycoplasma pneumonia must be diagnosed through some auxiliary tests.
