Had a cbc bloodtest done by my GP. My BUN/Creatinine level was 21 (range 9-20) BUN was 28 (range 6-24) Creatinine 1.31 (range 0.76- 1.27) I supplement with creatine and have been eating a lot more protein per day. I only had about 1 glass of water before the test. These numbers don't look alarming to me but my GP is kind of freaked out since their elevated from test results 2 years ago. I didn't mention the creatine supplentation or additional protein intake since he's just a mainstream type doctor. Anyone have any input?
