To diagnose biliary dyskinesia (BD) in children, a method of urine alpha-amylase measurement is offered. It is based on the presence of a direct and close correlation between amylase activity and the amount of endogenous cholecystokinin-pancreozymin in the same portion of the urine. It is concluded that fractional measurement of urine alpha-amylase can be used for diagnosing BD in childhood as a tentative test. It is advisable that it may be used for examining younger children and in cases where the employment of other methods of examination is not feasible.
