Alkaline phosphatase Alkaline phosphatase originates from many tissues in the body. In cats, the most common causes of increased alkaline phosphatase are liver and bone disease. ALT ALT is an enzyme produced by liver cells. Liver damage causes ALT to increase in the bloodstream. ALT elevation does not provide information as to whether the liver disease is reversible or not.
Amylase helps the body breakdown sugars.
Sometimes pancreatitis is difficult to diagnose and some dogs and cats with pancreatitis will have normal amounts of amylase in the blood. Lipase is another pancreatic enzyme which is responsible for the breakdown of fats and which may be increased in patients with pancreatic inflammation or cancer. Bile acids Bile acids are produced by the liver and are involved in fat breakdown. A bile acid test is used to evaluate the function of the liver and the blood flow to the liver. Patients with abnormal blood flow to the liver, a condition known as portosystemic shunt will have abnormal levels of bile acids.
