A BUN:creatinine ratio >30 can suggest a GI bleed. One may look at the BUN / Creatinine ratio to help determine the cause of renal failure. The ratio of BUN to creatinine is usually between 10:1 and 20:1.
WebThe Blood urea nitrogen (BUN): Creatinine Ratio (BCR) is a renal function indicator, commonly used to determine the potential cause of acute renal failure (ARF). BUN and creatinine are two metabolites steadily produced in the body. BUN is filtered in the nephrons and then reabsorbed in the blood, whereas creatinine is filtered and then … Webthe proximal tubule (PCT). Hence the increased BUN in prerenal AKI is attributed to two reasons: low GFR and increased reabsorption at the PCT. Creatinine goes up for only …

WebIn renal failure, blood urea nitrogen and serum creatinine usually rise in tandem; the normal BUN: Cr ratio is 10-15: 1. Disproportionate rises in BUN: Cr (> 20: 1) often imply pre-renal azotemia but may be caused by increased protein catabolism or an excessive protein load. In this study we look …
WebATN must be differentiated from prerenal azotemia because treatment differs. In prerenal azotemia, renal perfusion is decreased enough to elevate serum blood urea nitrogen (BUN) out of proportion to creatinine, but not enough to cause ischemic damage to tubular cells.
