Apart from viruses, hepatotoxins, hereditary metabolic disorders, immunological factors and cholestasis may cause chronic hepatitis both clinically and histologically. As far as the etiology is concerned, a complete history can be very helpful. The clinical examination, however, is rarely diagnostic. Nevertheless, some clinical signs (e.g. ascites, splenomegaly, spider naevi) are suggestive of cirrhosis. The activities of gammaglutamyl transferase and ALT in the serum are augmented in most of the patients with chronic hepatitis independent of its etiology. Electrophoresis reveals disturbance of serum albumin and globulin ratios. "Basic' laboratory tests are supplemented by carefully selected additional investigations (e.g. immunological tests) according to the history and clinical data of the individual patient. Retrograde cholangiography is diagnostic in the majority of patients suffering from primary-sclerosing cholangitis. Liver histology, best obtained during laparoscopy, allows classification (and prognosis) of the underlying liver disease in many patients. Results of iron and copper determination in liver tissue are diagnostic in cases of congenital liver disease (hemochromatosis, M. Wilson).
