What are normal liver enzyme levels in a healthy individual?

Liver tests: There are about eight or 10 tests which can be termed a "liver test". Each of them has different normal values. In addition, some of the normal values vary depending on which lab performs the test. Having said all that, a good approximation of all the liver test normal values can be found here: http://www.mayoclinic.org/tests-procedures/liver-function-tests/basics/results /prc-20012602
