What is GT – gamma-glutamyltransferase?
GT is a cell membrane-bound enzyme that is mainly found in the liver, pancreas and kidneys. GT, gamma-glutamyltransferase, ALP (alkaline phosphatases), AST and ALT are markers that can measure liver values together.
What do elevated and high GT values mean?
High levels of GT in the blood can indicate liver damage and should be monitored if liver or biliary tract diseases are suspected. Elevated GT levels are seen in diseases such as biliary obstruction, liver cancer, pancreatitis and pancreatic cancer.
Lower elevated levels may be due to infectious hepatitis, hepatic steatosis, diabetes, obesity, high alcohol consumption and certain medications.
An elevated GT level should be assessed together with other liver parameters.
