The AST can be high w/ liver disease, skeletal muscle diseases (myositis and mulcular dystrophy), trauma, pancreatitis
, renal infarct, eclampsia, cancer, cerebral damage
, seizures, alcohol, heart tissue disease (heart attacks, pericarditis), and infections in the bloodstream. Medicines: intramuscular injections, corticosteroids, primidone, antibiotics.
I have had an elevated AST from time to time, but then it will go back to normal. I'm pretty sure they look at the overall picture.
