Low GGT cholestasis points towards progressive familial intrahepatic cholestasis type 1-2 and 4-6, bile acid synthesis disorders, tight-junction protein type 2 deficiency and some forms of hypopituitarism. Classic galactosemia is generally not included in the differential diagnosis of low GGT cholestasis.

Conversely, high GGT cholestasis could point to other causes, like biliary atresia, where there may be no need to stop breastfeeding.
