The Bronchiolitis CPG Team recommends not routinely obtaining laboratory tests such as CBC & Diff w/platelets, Basic Metabolic Panel, Blood Culture, RSV antigen detection, Flu A &B antigen, or chest x-ray for the infant who is presenting for the first time with symptoms of bronchiolitis. The recommendation concurs with the AAP (2006) and Scottish Intercollegiate Guidelines Network (SIGN, 2009) bronchiolitis guidelines. RSV antigen testing maybe obtained if applied to cohorting infants on inpatient units. Bronchiolitis is diagnosed based on history and physical examination (AAP, 2006). We placed high value on avoiding unnecessary medical testing and reduction of discomfort to the patient.
