- acute viral hepatitis a moderate increase.
- chronic viral hepatitis GGT is a little above
the upper reference limit or within the range.
32GGT

- Clinical significance
- ???????????????GGT--??????,ALT?AST--N???
- GGT shows a far greater increase than the ALT
and AST,the GGT/AST ratio is gt6. - GGT as marker of alcoholism
33GGT

- ???????GGT--????
- Cholestasis GGT increases earlier and persists
longer than ALP .it is elevated in practically
all cases of extra or intrahepatic cholestasis.
