An abnormally high level of creatinine in the blood may indicate that the kidneys are damaged or impaired. Creatinine is one of the substances that our kidneys normally remove from the body. The toxins are then stored in the bladder and removed in urine. The nephrons remove waste products, excess water, and other impurities from the blood.

Our kidneys are full of small blood-filtering structures called nephrons. The GFR is considered to be the best measure of kidney function.

Frequently, healthcare providers will use your blood creatinine level, along with your age, race, sex, and other factors to calculate your glomerular filtration rate (GFR). Creatinine levels are often assessed to determine how well the kidneys are working or before and after dialysis to monitor effectiveness of treatment. As such, BUN tests can also be used to track the progress of a kidney disease.Ĭreatinine is a waste product that forms when creatine (a supplier of energy to the muscles) breaks down. An unusually high BUN level may indicate that the kidneys are unable to effectively remove urea from the blood. A blood urea nitrogen (BUN) test measures the amount of nitrogen in our blood that has been created by urea and is typically ordered to assess kidney function. Healthy kidneys should filter out urea and other chemical waste products from the blood through urine. Urea then travels through the liver and into the kidneys via the bloodstream. The nitrogen reacts with other elements in our bodies (such as carbon, hydrogen, and oxygen) to form urea. After a protein is deconstructed, the liver produces nitrogen-containing ammonia.

Blood urea nitrogen is a waste product formed during the process in which our bodies break down proteins.
