OBJECTIVES: To determine whether the concentration of pepsin in the saliva sample changes according to the storage period of the sample.
METHODS: Forty eight patients with suspected laryngopharyngeal reflux were included in this study. Saliva samples were collected from each patient and each sample divided into six and stored for different period of time. Pepsin concentration was measured using enzyme-linked immunosorbent assay. A comparison was made between the pepsin concentration measured immediately and the concentration measured after storage for 1 week, 2 weeks, 1 month, 3 months, and 6 months.
RESULTS: No significant difference in pepsin concentrations were detected between the sample analyzed immediately and those analyzed at 1 week, 2 weeks, 1 month, and 3 months after saliva collection. A significant difference in pepsin concentration was observed in the sample analyzed immediately and the sample analyzed 6 months after saliva collection.
CONCLUSIONS: Pepsin concentration in saliva samples did not demonstrate a significant difference between the concentration measured immediately and the concentration measured 3 months after saliva collection, although a significant difference was observed in the concentration measured 6 months after collection.
