0 – 15 Yrs = 8 – 50 IU/L

The enzyme alanine transferase is involved in the alanine amino acid's metabolism. Although ALT is active in a variety of tissues, the liver has the most of it. The enzyme is released into the blood when the liver is injured.
This test might be requested for several reasons including suspected symptoms of liver disease or damage or lack of blood flow to the liver or certain medications or poisons.
