Many factors may result in elevated creatinine and BUN numbers, but we will only talk about those numbers caused by kidney damage here. So you should make sure you have already been diagnosed with kidney diseases. The normal range of creatinine level for men is 0.6-1.2mg/dl; for women is 0.5-1.1mg/dl. The normal range of BUN numbers for adults is 9-20mg/dl.
Then came the third test which showed my creatinine level to be 1.33 mg/dl. Almost to the 1.30 mg/dl mark for my age(36yrs) and other criteria. I came to the conclusion that the reason for my elevated creatinine level was due to the use of creatine. So I jumped back on creatine using the recomended dosages.
