The diagnosis of liver disease depends primarily on an adequate history and a physical examination. These should indicate the correct diagnosis in two thirds of the cases; the addition of liverfunction tests assists in the differentiation of hepatic disease. However, there remains a group of patients in whom a precise diagnosis is not made by means of history, physical examination, or so-called liver-function tests. In these, morphologic examination of hepatic tissue may confirm a clinical diagnosis or change a clinical impression, although liver biopsy can also be disappointing as a diagnostic test.
