My b12 levels are always 1200-1300 and my alanine levels are high. does it neccesarily mean something is wrong with the liver?

Maybe: Elevated B12 means nothing. You're making more of the binder protein for some reason. Nobody measures alanine, but if your alanine amino transferase (ALT / SGPT) levels are up, you'll want to know why -- if it's not alcohol, you may have a medication allergy, a viral hepatitis, iron overload, Wilson's, autoimmune hepatitis, or it may be your body's way of asking for more exercise.
