Occasionally, a health practitioner will look at the ratio between a person's BUN and blood creatinine to help determine what is causing these concentrations to be higher than normal. The ratio of BUN to creatinine is usually between 10:1 and 20:1.An increased ratio may be due to a condition that causes a decrease in the flow of blood to the kidneys, such as congestive heart failure or dehydration.he ratio of BUN to creatinine is usually between 10:1 and 20:1.

Blood urea nitrogen (BUN) measures the amount of urea nitrogen in bloodstream. Urea is formed in liver as the end product of protein metabolism and digestion. Urea is transported to the kidneys for excretion. A normal range for blood urea nitrogen is generally 8 to 24 mg/dl for adult males and 6 to 21 mg/dl for females.Generally, a high blood urea nitrogen level means that the kidneys are not performing well, particularly if the result is above 50mg/dl.n adult men, normal range of serum creatinine is 0.9-1.3mg/dl; while in adult women, normal range of creatinine is 0.6 to 1.1mg/dl. A muscular young man will have a higher normal creatinine result than the senior people with poorer health conditions.
