ok, i can rule out the renal tubular kidney thing. i dont have any problems with my liver or kidneys. my ALT level was just over the normal limit. it did say that hypo thyroid and diabetics can have high ferritin and low iron. i dont take metformin altho i am supposed to. i try to control by diet, but im not doing so well with that either. i still dont know what will happen if i take an iron supplement, will it make my ferritin level worse?
