GGT
  • ? ? ? ?
  • Clinical significance
  • ???????GGT--??,
  • ????????????? GGT--N,?GGT????,????????????
  • acute viral hepatitis a moderate increase.
  • chronic viral hepatitis GGT is a little above
    the upper reference limit or within the range.

32
GGT
  • ? ? ? ?
  • 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

33
GGT

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