Onderzoeken van plasma of serum moeten bestaan uit: glucose, totaal cholesterol, ureum, creatinine, totaal eiwit, albumine en ten minste twee enzymen die indicatief zijn voor hepatocellulaire effecten (zoals alanineaminotranferase, aspartaataminotransferase, alkalisch fosfatase, gammaglutamyltranspeptidase en sorbitoldehydrogenase).
Investigations of plasma or serum should include: glucose, total cholesterol, urea, creatinine, total protein, albumin and at least two enzymes indicative of hepatocellular effects (such as alanine aminotranferase, aspartate aminotransferase, alkaline phosphatase, gamma glutamyl transpeptidase and sorbitol dehydrogenase).
