All About Gamma-Glutamyl Transferase (GGT Blood Test)
What is a GGT Test? A Gamma-glutamyl transferase test is a blood test conducted to check on the health of a liver. The liver consists of several forms of protein (also known as an enzyme) including GGT and if any damage is caused to the liver, the enzyme tends to leak and mix with the bloodstream. A health care provider conducts the GGT blood test to identify the levels of GGT in the veins. It is normal to find the enzyme mixed with the blood, but if it exceeds the normal level, it becomes a matter of concern as the bile duct and liver may be at risk. What is the need for a GGT test? A GGT blood test is one in the sequence of blood tests termed a liver panel. In this sequence, alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and bilirubin are also determined to recognize the exact condition of the liver. The normal level of GGT in the body should be between 0 to 30 I/UL and if it increases, it is a clear sign of unhealthy liver that may ...
