title: A critical examination of the value of combined determinations of lecithin:cholesterol acyltransferase and lipoprotein-X in the differential diagnosis of liver disease.
abstract: The suggestion that combined determinations of lecithin: cholesterol acyltransferase activity and lipoprotein-X can be used to distinguish between patients with intrahepatic cholestasis and extrahepatic biliary obstruction has been studied. Of 21 patients who were lipoprotein-X positive and in whom an unequivocal diagnosis was made, 11 had intrahepatic cholestasis and 10 extrahepatic obstruction. The range of plasma lecithin:cholesterol acyltransferase activity was similar in the two groups and did not enable distinction to be made between them.
