My RDW has been elevated since MG symptoms began prior to prednisone and cellcept. The highest it has been is 28 and has never been normal since. When my MG is bad I get anemic and the RDW goes way up. I also had sphereocytes in my blood so I think I have an autoimmune hemolytic anemia, it only seems to kick off when the MG is bad or vice versa. I suggest you ask for a manual differential with your next blood work. MGers often have more than 1 autoimmune disease. Lupus, pernicious anemia and autoimmune hemolytic anemia are often found in MGers that might cause the anemia and high RDW. Talk with your doctor.

good luck
