Serum Glutamic Pyruvic Transaminase or ALT is an enzyme found primarily in the liver but also to a lesser degree, the heart and other tissues. It is useful in diagnosing liver function more so than SGOT levels. Decreased SGPT in combination with increased cholesterol levels is seen in cases of a congested liver.
Alanine Aminotransferase (ALT). This is an enzyme that can only be found in the liver. When cells become damaged in the liver, the ALT enzyme will rise. The increase in the ALT enzyme is directly related to the amount of liver cells which are damaged. It's important to note that an increase of ALT enzyme can also be caused by other conditions in the body, such as heart failure and anemia. This test cannot be relied on solely to determine if your dog has liver disease.
