What Is High Liver Function?

High liver function is determined by a liver enzyme test. WebMD warns that elevated liver enzyme levels, or high liver function, is a potential indicator of liver damage.

Doctors often perform a liver enzyme test as part of the annual physical, or if certain risk factors are present. The test is performed as part of the blood panel. The Mayo Clinic staff counsels that a high level of liver enzymes in the blood is often a temporary condition. Following a blood test indicating a high liver enzyme level, the doctor reviews her patient's alcohol use, medications, and further test results to identify the specific cause of the high liver function.
