Parotid Saliva Test Compared with Pancreozymin-Secretin Test in Diagnosis of Pancreratic Disorders

Comparison between the pancreozymin-secretin test and the parotid saliva test was made in regard to the reliability as diagnostic means for pancreatic disorders on 22 subjects in total, consisting of 12 patients with pancreatic disorders and 10 with non-pancreatic disorders. The data indicated that in this series a positive parotid saliva test is 90.9% accurate in diagnosing pancreatic disorders, whereas a positive pancreozymin-secretin test is only 50%. It was noteworthy that the pancreozymin-secretin test gave false positive results in 8 of 10 patients with non-pancreatic disorders, whereas the parotid saliva test gave negative results in all these cases.
