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.
The normal range for serum creatinine (in the blood) is usually between 0.6 and 1.3 milligrams per deciliter (mg/dL) although it varies between labs, between men and women, and by age.... A high serum creatinine level means your kidneys aren't working well.f they are healthy, the kidneys typically keep blood creatinine levels in a normal range. As such, creatinine levels are a fairly reliable indicator of kidney function. If the kidneys become impaired for any reason, the creatinine level in the blood will rise.
