I received the results of my CBC. It is all normal except my RDW (red blood cell distribution width) was 15.3 (range is 11-15). It was elevated once before; however, all the other CBC blood tests that I have ever taken have always had normal RDW's. Is it normal to have periodic elevations in RDW while on TRT? Is it simply an indication that the TRT is stimulating new red blood cell production?

Thanks
