DIFFERENTIAL DIAGNOSIS METHOD FOR IDENTIFYING THE CASES OF CHRONIC PANCREATITIS AND PANCREAS CARCINOMA Russian patent published in 2000 - IPC

FIELD: medicine. SUBSTANCE: method involves determining phospholipase A enzyme activity and carbohydrate antigen 19.9 concentration, leukocyte migration index using data concerning inhibition of reaction with pancreas antigens. Differential diagnosis index is calculated from ratio of hundredfold value of phospholipase A enzyme activity to the product of leukocyte migration index and carbohydrate antigen 19.9 concentration. The calculated value being greater than 19.8, chronic pancreatitis is to be diagnosed. The value being less than 14.4, pancreas carcinoma is to be diagnosed. The value being between 14.4 and 19.8, the case of no pathologic changes in the pancreas is to be stated. EFFECT: high accuracy of diagnosis; high safety degree.
