I was searching for some information and came across this website of liver function test descriptions. It may be of benefit to you and another place here that you can refer a member to that has a question regarding these tests. I'd also like to suggest that anyone with questions regarding their personal test results and the accuracy of them, should discuss them with their doctor and health team. I hope this may help with the general understanding of these tests.
