Liver enzyme data collected from 218 patients with liver disease
(Plomteux, 1980). The laboratory profile consists of enzymatic
activity measured for four liver enzymes: aspartate
aminotransferase (AST
), alanine aminotransferase (ALT
),
glutamate dehydrogenase (GLDH
) and ornithine carbamyltransferase
(OCT
).

hepatitis (3) and post-necrotic cirrhosis (4).
AST
: Aspartate aminotransferase (in U/L)
ALT
