In medicine, the urea-to-creatinine ratio (UCR [1]), known in the United States as BUN-to-creatinine ratio, is the ratio of the blood levels of urea (mmol/L) and creatinine (Cr) (μmol/L). BUN only reflects the nitrogen content of urea (MW 28) and urea measurement reflects the whole of the molecule (MW 60), urea is just over twice BUN (60/28 ...
BUN is an indication of kidney health. The normal range is 2.1–7.1 mmol/L or 6–20 mg/dL. [1]The main causes of an increase in BUN are: high-protein diet, decrease in glomerular filtration rate (GFR) (suggestive of kidney failure), decrease in blood volume (hypovolemia), congestive heart failure, gastrointestinal hemorrhage, [5] fever, rapid cell destruction from infections, athletic ...
Outside the United States, blood tests made up of the majority of the same biochemical tests are called urea and electrolytes (U&E or "U and Es"), or urea, electrolytes, creatinine (UEC or EUC or CUE), and are often referred to as 'kidney function tests' as they also include a calculated estimated glomerular filtration rate. The BMP provides ...
The blood urea nitrogen (BUN) test is a measure of the amount of nitrogen in the blood that comes from urea. It is used as a marker of renal function, though it is inferior to other markers such as creatinine because blood urea levels are influenced by other factors such as diet, dehydration, [35] and liver function.
Azotemia (from azot 'nitrogen' and -emia 'blood condition'), also spelled azotaemia, is a medical condition characterized by abnormally high levels of nitrogen-containing compounds (such as urea, creatinine, various body waste compounds, and other nitrogen-rich compounds) in the blood.
Just before the College Football Playoff kicks off, Dan Wetzel, Ross Dellenger, and SI's Forde provide a final preview of the 12-team bracket. They discuss the potential for five to six different ...
Blood urea nitrogen (BUN) - Also measured using a BMP or CMP, blood urea nitrogen is an indicator of how much nitrogen is in the blood at the time of the phlebotomy. The kidney is responsible for excreting nitrogenous substances in the urine, so an elevated BUN usually indicates that the kidney is not functioning appropriately. [32]
