Can a blood routine detect mycoplasma pneumonia?

Mycoplasma pneumonia can not be detected by blood routine, and the total number of white blood cells can only be detected by blood routine, and mycoplasma pneumonia can be detected by condensation set test, Mycoplasma pneumoniae isolation and culture, mycoplasma antibody titer detection, and Mycoplasma pneumoniae antigen detection.

1. Condensation set test: The condensation set test is of great significance for the diagnosis of mycoplasma infection, especially mycoplasma pneumonia. Approximately two-thirds of patients have a positive condensation test with a titer of 1:32 or greater 2 weeks after 2 weeks of onset. If the titer increases gradually, it is more diagnostic.

2. Protoplasma antibody titer test: If the serum mycoplasma IgM antibody ≥ 1:64, or the convalescent antibody titer is 4-fold higher, the diagnosis can be further confirmed.

3. Mycoplasma pneumoniae isolation and culture: isolation of Mycoplasma pneumoniae from the patient's nasopharynx, throat, body fluids or pleural fluid is a reliable standard for diagnosing Mycoplasma infection.

4. Antigen detection of Mycoplasma pneumoniae: Mycoplasma pneumoniae antigen is detected directly from respiratory specimens, which can be used for rapid diagnosis in early clinical stage.

The results of routine blood tests alone cannot accurately determine whether it is mycoplasma pneumonia, and it is necessary to make a comprehensive judgment based on the characteristics of the medical history and other examination results, and it is recommended to clarify the cause under the guidance of a doctor.
