What it is

ASAT (aspartate aminotransferase, AST) is an enzyme found in the liver, the heart and the muscles, where it helps the body process amino acids. A small amount is always present in the blood. Because it comes from several tissues, it is read together with the other liver values and CK.

What affects your levels

Hard or unfamiliar exercise can raise AST for a few days because it is released from the muscles. Alcohol, a diet high in sugar, body weight, some medicines and a recent infection also affect the level.
