What are the tests that need to be done for mycoplasma pneumonia in children?

There are several tests that may be done for mycoplasma pneumonia in children:

1. Peripheral blood test: most of the white blood cells are normal, and there may be an increase, and there may be a decrease in leukopenia if combined with viral infection.

2. Blood biochemical examination: ESR increased rapidly, and anti-O and antibody titers were normal. Elevated alanine aminotransferase may occur in the presence of liver damage.

3. Mycoplasma detection: In the early stage, children can use PCR method to detect secretions such as sputum and mycoplasma DNA in lung tissue, and mycoplasma can also be isolated and cultured from sputum, nasal secretions, and throat swabs.

4. Red blood cell condensation test: Cheng is positive, and the titer is above 1:32, which has certain significance for the diagnosis of mycoplasma pneumonia in children.

5. Sputum, nasal and throat swab culture: it can confirm the presence of Mycoplasma pneumoniae, but it takes about 3 weeks.

6. X-ray examination and/or CT of the lungs: the following conditions may occur, such as hilar shadow widening, bronchopneumonia changes, interstitial pneumonia changes, and uniform consolidation. Subtle signs and prominent opacities on chest x-ray are a hallmark of the disease. Sometimes with pleural effusion, x-rays of the lungs change rapidly. Lung CT can help distinguish whether there is a pleural effusion, pneumothorax, bronchiolitis obliterans, etc.

7. Electrocardiogram: If necessary, electrocardiogram and cardiac ultrasound should be checked to determine whether there is myocardial damage, even myocarditis, pericarditis, etc.
