L-lactate dehydrogenase (LDH) is an intracellular enzyme that converts lactic acid to pyruvic acid, elevated levels indicating cellular death or damage (4).
The quantities measured and the corresponding analyzers were as follows: serum concentrations of apolipoprotein A1, apolipoproteins B, bilirubin (nonesterified), chloride, cholinesterase, HDL-cholesterol, L-lactate dehydrogenase, lipoprotein(a), pancreatic a-amylase, peptidyl dipeptidase A, transferrin, and triacylglycerol lipase were measured with the Modular System (Roche Diagnostics); serum magnesium concentrations were measured with the Dimension RxL (Dade Behring); serum concentrations of CA 15-3 antigen, CA 19-9 antigen, CA 125 antigen, a-fetoprotein, [[beta].
