Diagnostic tests for premature bronchiolitis

Reading time: 1 min

No tests should be performed to diagnose bronchiolitis in an out-of-hospital setting, except for oxygen saturation via transcutaneous pulse oximetry.

Test that measures oxygen saturation in blood by transcutaneous pulse oximetry
  • Oxygen saturation. Transcutaneous pulse oximetry (measuring oxygen via the finger) is a simple, painless method. It is one of the most practical ways to measure the concentration of blood oxygen (blood PaO2). Therefore, it allows us to discern which cases require oxygen supply, (when saturation is lower than 95%).
Chest X-ray to the baby affected of bronchiolitis
  • Chest X-ray. It may be useful for patients who have been hospitalised and are not progressing as expected, or when another pathology is suspected. Bronchiolitis has no typical radiological pattern.
Blood count
  • Blood count. This type of analysis is not usually carried out when assessing infants with typical bronchiolitis.
