What are normal ALT values? 4-36 units/L
What does AST test measure? Aspartate Amniotransferase--an enzyme found in the Liver and a few other places, particularly the heart and skeletal muscles. When there is injury to these tissues, cells lyse and the AST level in the bloos stream rises.
What might elevated AST indicate? Liver disease or Heart disease, can indicate an AMI. (When AST levels are increased in presence of CPK, it indicates myocardial damage)
Normal AST value? 0-35 units/L

Normal Lab value for Potassium? 3.5-5 mEq/L
BUN measures? Renal function and indirectly, liver function. When proteins are taken in, they are broken down into amino acids. In the liver, these amino acids are catabolized and ammonia is created as a result of that. The ammonia molecule combines to form urea
