Interpretation of Liver Function Tests / 대한소화기학회지

ABSTRACT

Liver function tests (LFT) are helpful screening tools to detect hepatic dysfunction. LFT are further used to categorize hepatic dysfunctions, to estimate the severity of hepatic disease, and for the follow-up of liver diseases. Since liver performs a variety of functions, no single test is sufficient alone to provide complete estimate of function of liver. Effective interpretation of the hepatic function panel requires knowledge of underlying pathophysiology and the characteristics of panel tests. This review includes a classification of liver diseases, which are commonly detected by routine LFT, a list of liver functions with appropriate tests for each function, and a guide to panel interpretation and further laboratory investigation.
