Pepsin A+Pepsinogen A [Mass/volume] in Lower respiratory specimen by Immunoassay
Active
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. (One unit of pepsin A=0.1ng/ml pepsin A is a measure of concentration (ng/ml) expressed in an arbitrarily defined unit.)

Part Description
LP206550-8 Pepsin A+Pepsinogen A
Pepsin is the principal proteolytic enzyme of vertebrate gastric juice. Pepsin's inactive precursor form, pepsinogen, is produced in stomach mucosa. The minor pepsins are designated "B", "C", and "D". "A" is the major component.
