Newborns have immature tracheal functions and low immune function; once neonatal pneumonia occurs, hospitalization is definitely required. The usual tests needed include the following aspects:

First, imaging tests, typically including chest X-rays or a CT scan of the lungs, are necessary to understand the extent, severity, and specific details of the lung lesions.

Second, tests related to infection are needed. This generally includes complete blood counts, C-reactive protein, procalcitonin, etc. In cases with significant throat phlegm, sputum culture and blood culture are also needed to identify the pathogen.

Third, an assessment of the child’s tracheal function and internal environmental status is required. This typically involves blood tests for liver function, kidney function, cardiac enzymes, electrolytes, etc., to enable a comprehensive assessment and accurate treatment.
