Blood picture is not a criterion for determining the onset of mycoplasma pneumonia; patients usually do not have high blood picture, which is high in about 1/4 of patients, but is not specific in determining pneumonia. In fact, mycoplasma pneumonia also has its own unique test results to determine it, such as antibody tests for mycoplasma pneumonia and condensation set tests, which support the diagnosis of mycoplasma pneumonia if the test results are high. In the case of advanced laboratories, there is also a mycoplasma culture, which takes a longer time and is usually used only in scientific research, and clinically if it is needed to guide treatment with it, which takes longer, hospitals usually do not use this test. Mycoplasma pneumonia is a common and high incidence disease, especially in children and adolescents who have a high proportion of the incidence of pneumonia. If one has pneumonia, it is usually covered in outpatient experience treatment for mycoplasma, because the treatment of mycoplasma pneumonia differs from that of common pneumonia. Common pneumonia is a Streptococcus pneumoniae infection and penicillin and cephalosporin are usually chosen, but mycoplasma pneumonia requires treatment with macrolides or quinolones, doxycycline, etc.
