I've had high GGT and ALT for the past few years but my last set of tests now show high AST and APL too and slightly high ferritin too. My previous imaging tests and the liver biopsy showed healthy liver, no PBC, no autoimmune hepatitis. There doesn't seem to be a link between lupus activity and the enzymes.
Have you experienced high liver enzymes due to lupus? My hepatologist and my rheumatologist can't agree whether mine are caused by lupus, they both seem to think that they aren't.
