GGT
Also known as Gamma-Glutamyl Transferase
What it is
Gamma-Glutamyl Transferase is a liver enzyme that rises when the liver or bile ducts are under stress, and it is particularly sensitive to alcohol intake.
Why it matters
GGT is one of the more specific liver markers for detecting early liver stress, especially from alcohol, since it tends to rise before the more commonly known liver enzymes (ALT, AST) do in that context. It's also used to help clarify the source of an elevated ALP result, since ALP can rise from either liver or bone conditions, and a normal GGT alongside elevated ALP points away from the liver as the cause. Reading it alongside the CMP's liver values gives a fuller picture of liver health than either provides alone.
GGT is one of the markers in Zaro's Signal panel and every tier above it.
