It has to do with your kidney function. My son has a high BUN level due to some meds that he takes. If it's not too high there may not be a problem. Also, if you were dehydrated when you had the blood work done that can cause a high BUN/creatine level. I wouldn't worry too much until you talk to your doctor.
