There are several types of tests for mycoplasma pneumonia

Understanding the examination items of mycoplasma pneumonia can help you diagnose it early, so what are the examination items for mycoplasma pneumonia? With this question, we consulted relevant experts, and the experts introduced the following content for us, let's find out together.

Tests for mycoplasma pneumonia:

1. The total number of white blood cells in the blood is usually within the normal range, but occasionally it can be elevated. 25% of patients have leukocytes over 10.0×109/L, and a few can reach (25.0~56.0)×109/L. Classification is a slight increase in neutrophils or eosinophils. Thrombocytopenia. Direct Coombs test may be positive. Erythrocyte sedimentation rate (ESR) may increase rapidly in the early stages of the disease.

2. The culture method is not helpful for clinical diagnosis due to the high nutritional requirements and slow growth of Mycoplasma pneumoniae, which requires observation for 10~30 days or longer. At present, the Hayflied medium recommended by the US Centers for Disease Control (CDC) is still used abroad, and the Martin medium or porcine lung digest based medium of the Capital Institute of Pediatrics is mostly used in China.

3. Serological methods are widely used serological diagnostic methods for the diagnosis of Mycoplasma pneumoniae infection, and those with a double serum titer of 4 times increased in the acute and convalescent phases, or a single serum titer of ≥ 1:32 are judged to be positive. It has a sensitivity of up to 90% and a specificity of 94%, and is only positive in the initial infection, and often does not occur in the second infection.

The above are the more common examination items for mycoplasma pneumonia in professional hospitals. Of course, the focus of the examination items for mycoplasma pneumonia in different hospitals is different, and everyone is required to choose a regular hospital for the examination of mycoplasma pneumonia.
