title: Abnormal liver enzyme levels. The spectrum of causes.
abstract: Asymptomatic patients with persistent elevation of liver enzyme levels require further tests to detect the cause of hepatobiliary injury. The magnitude of enzyme elevation does not reflect severity of disease. The pattern of enzyme elevations, ie, hepatocellular or cholestatic, should be used to guide the evaluation.
