[Biochemical criteria of intrahepatic cholestasis in hepatitis B].

Properties differentiating 13 biochemical indexes of cholestasis within a group of patients suffering from acute virus hepatitis were examined. It has proved the existence of a set of parameters of optimal properties differentiating separate states of cholestasis. This set includes concentrations of bilirubin and cholesterol esters, together with the activity of alkaline phosphatase. The variables formed a function enabling to differentiate mathematically+ the states with and without cholestasis.
