High Urea/Creatinine Ratios in Blood and Urine

I have a quite elevated blood BUN/Creatinine (calculated 21, ref. 9-20) and a very elevated ratio in the urine (spot) at 32 (ref. 2.5-2.8). Both urea and creatinine value in blood and also in urine are within lab ref. ranges. I am concerned but my doc is not and said the urine spot is not really relevant. He did not really look the ratio of the blood values,

Should I be concerned and intervene somewhere?

I tend to have a moderately higher protein intake in my diet. I am 57 with mild symptoms of BPH and an elevated post void residual which is being treated with tamsulosin.

Sorry to reply on myself but ... is there really nobody out there to comment on this condition?
