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 ...
Measurements of urea and creatinine (Cr) in the blood are used to assess renal function. For historical reasons, the lab test measuring urea is known as "blood urea nitrogen" (BUN) in the US. The BUN:Cr ratio is a useful measure in determining the type of azotemia and will be discussed in each section below. A normal BUN:Cr is equal to 15. [3]
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 ...
An alternative estimation of kidney function can be made when interpreting the blood plasma concentration of creatinine along with that of urea. BUN-to-creatinine ratio (the ratio of blood urea nitrogen to creatinine) can indicate other problems besides those intrinsic to the kidney; for example, a urea concentration raised out of proportion to ...
One’s biological age, which measures the body’s physiological state, may help predict who is at risk for developing colon polyps, a known risk factor for colorectal cancer.
Few foods are more appetizing to people than a juicy steak. Grilled to order and garnished with herbs like basil and chives, sauces such as au jus, peppercorn and A1, or vegetables like grilled ...
Just after winning a gold medal in the individual vault final in Paris on Aug. 3, Biles spoke during a press conference about the future of her signature vault. "This is my last, definitely ...
