In brief: BUN and creatinine

If you have high BUN and creatinine levels, you may be dehydrated or you may have chronic kidney disease.
Ask the physician who ordered the blood test for an opinion as to the cause of the high levels in the blood. The physician knows the patient best and can give a more meaningful answer to your question. Good luck.
