GGT in cats what is it? - briefly
GGT, or gamma-glutamyl transferase, is an enzyme found in cats that helps assess liver function and detect potential liver or biliary tract disorders. Elevated levels of GGT in blood tests may indicate liver damage or disease.
GGT in cats what is it? - in detail
Gamma-glutamyl transferase (GGT) is an enzyme found in various tissues, with significant concentrations in the liver, kidneys, and pancreas. In cats, GGT is primarily used as a diagnostic marker to assess liver health and function. This enzyme is involved in the metabolism of glutathione and the transfer of amino acids across cellular membranes. Elevated levels of GGT in a cat’s blood can indicate liver damage, bile duct obstruction, or other hepatobiliary disorders. Conditions such as cholangitis, hepatic lipidosis, or neoplasia may lead to increased GGT activity. However, GGT levels alone are not definitive; they are typically evaluated alongside other liver enzymes like ALT, ALP, and bilirubin to provide a comprehensive assessment. It’s important to note that GGT is less sensitive in cats compared to dogs, and its elevation may not always correlate with the severity of liver disease. Veterinary professionals often interpret GGT levels in conjunction with clinical signs, imaging, and other diagnostic tests to determine the underlying cause and appropriate treatment. Monitoring GGT levels can also help track the progression of liver disease or the effectiveness of therapeutic interventions. Early detection and management of elevated GGT can significantly improve outcomes for cats with liver-related conditions.
