The blood urea nitrogen (BUN)/creatinine ratio is a strong prognostic indicator in patients with acute decompensated heart failure (ADHF). In medicine, the BUN to creatinine ratio is the ratio of two serum laboratory values, the blood urea nitrogen (BUN) (mg/dL) and serum creatinine (Cr) (mg/dL). Also, low levels of BUN/Creatinine can be due to certain renal damages that cause a reduction and reabsorption of BUN. Abnormal BUN/Creatinine Ratio Treatment 2013-12-26 22:54. Interpreting BUN creatinine ratio. BUN-to-creatinine ratios are helpful for gauging the health of the kidneys and uncovering underlying, related health issues.

Kidney Disease :: Bun/creatinine Ratio 20.9 Apr 14, 2014. "is a low bun/creatinine ratio (8.3) something to worry about if bun is at 8 mg/dl and creatinine is at 0.96 mg/dl, both within the normal range?" Alternatively, a BUN:creatinine ratio of 10:1 suggests an intrinsic renal disease, such as glomerulonephritis or acute tubular necrosis. Please Note: If results for BUN and Creatinine are both within the normal reference range, the BUN/Creatinine ratio will not be reported (not applicable). When the ratio approaches 20:1, it suggests a problem with bloodflow to the kidney; this may be caused by conditions such as heart failure or shock 1. Reduced renal perfusion, e.g., congestive heart failure, or recent onset of urinary tract obstruction will result in an increase in BUN/Creatinine ratio. Numerous conditions or factors can lower BUN and creatinine levels. BUN Creatinine Ratio can help a physician to decide what has caused your renal failure or if you have renal failure at all.

Concentration of creatinine in the blood depends upon the amount of muscle that you have and the ability of your kidneys to excrete creatinine. While there is no such thing as abnormally low creatinine levels, ... Urine creatinine levels are used to calculate other values such as protein creatinine ratios or calcium creatinine ratios. BUN Creatinine ratio interpretation >20: indicates pre-renal cause of ARF; 10-20: is a normal value or indicates post-renal cause; <10: indicates renal cause of ARF. Causes of a High BUN-to-Creatinine Ratio Higher than normal values can be caused by acute kidney problems. Too high a value points to dehydration, and too low a value to kidney damage. BUN-creatinine ratio helps determine the cause of sudden dysfunction of kidney or acute renal failure. How are your other liver and kidney tests?

As for the normal values it depends on the age. An elevated BUN:Cr due to a low or low-normal creatinine and a BUN within the … The BUN to creatinine ratio calculation formula is as follows: BUN to Creatinine Ratio = Blood urea nitrogen / Serum creatinine.

Increased urea formation also results in an increase in the ratio, e.g., gastrointestinal bleeding, trauma, etc. Because the body produces much more BUN than creatinine, the ideal ratio lies somewhere between 10:1 and 20:1. The BUN/Cr ratio is normal at 10 to 15:1 in ATN (intrarenal), but is often greater than 20:1 in prerenal disease due to the increase in the passive reabsorption of urea that follows the enhanced proximal reabsorption of sodium and water . The BUN-to-creatinine ratio is determined by dividing the patient's blood urea nitrogen result by their serum creatinine. Maybe it’s also for … Unlike BUN, creatinine levels remain relatively stable in healthy people.
