Term Description

The presence of gastric pepsin A in a patient's airway is a marker for aspiration and assists in the diagnosis of gastroesophageal reflux. Chronic aspiration of gastric contents may worsen lung disease in premature infants, or other mechanically ventilated patients. PMID: 16954956 This assay detects both pepsin A and pepsinogen A and does not differentiate between the two. A level of less than 3 is considered in range.
