[What shall I do with a patient with elevated liver tests?].

In this article you will find a short reminder on the lab tests of the hepatic function and of the hepatic diseases. It shall help treat a patient with elevated liver tests. We will distinguish between an elevation of the liver enzymes of more/equal 5x and less than 5x the norm. An elevation of more/equal 5x the norm of the liver enzymes requires a rapid work-up. When the elevation is less than 5x the norm, one can proceed in two steps. A life style modification can be proposed after excluding a viral hepatitis and a hemochromatosis. If the liver enzymes still remind elevated, rarer causes must be searched.
