Question: is ggt part of liver function test?
Answer: The GGT test is also part of a series of tests known as a liver panel, which checks the levels of other liver enzymes, such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and bilirubin. Someone with an elevated ALP level may need a GGT test to narrow down the cause.
