Liver enzyme predicts overall health ?

The American Association for the Study of Liver Diseases (AASLD) recommend that both doctors and the public should pay more attention to the levels of the liver enzyme alanine aminotransferase (ALT) in blood as there is growing evidence that ALT is a marker of general health. Mayo Clinic College of Medicine observed an increased risk of death for subjects with elevated levels of ALT. Elevated levels of the enzyme increased the risk of death by 63 percent.
