Bun and creatinine levels are in normal range but bun/creatinine ratio was high at 26.4 on a ref range of 7-21.7. what could be causing this elevation? egfr is at 117. having severe fatigue and tachycardia. cardiac issues ruled out already?

With a normal GFR your kidney function is fine. An elevated BUN can be caused by many things. Reduce your protein intake and have the test repeated in a few weeks. If still high pl see your doc. good luck
