[Discriminatory analysis applied to bromsulphalein (BSF) kinetics: its use in the differential diagnosis of post-alcoholic chronic hepatopathies].

Plasma disappearance rate of sulfobromophthalein (BSF), a second stage diagnostic methodology for hepatic illness, has been widely used in testing functional derangement of chronic alcoholic liver disease. However kinetics parameters show wide range of values so it is difficult, in the single patient, to make a reliable differential diagnosis between chronic alcoholic hepatitis and cirrhosis, by this mean. The Author using BSF kinetics parameters calculated a discriminatory function which allows to assess the nosography of alcoholic hepatic affection with a low grade of mistake in the single patient; the suppose that this function improve the sensitivity of BSF plasma disappearance rate and make this second stage procedure more useful in testing chronic alcoholic liver diseases.
