WebNov 19, 2024 · The ratio is indicative of prerenal injury when the BUN-to-creatinine ratio is greater than 20. The ratio is may also be useful for diagnosing gastrointestinal bleeding in some patients who do not present with overt blood loss. In children, a BUN-to-creatinine ratio of 30 or greater has a sensitivity of 68.8% and a specificity of 98% for upper ... WebBun/Cr has been used for the differentiation of prerenal renal dysfunction from intrinsic renal parenchymal disease. Brisco et al reported that elevated admission BUN/Cr identifies ADHF patients with possibly reversible renal dysfunction by HF treatment, but also noted that elevated BUN/Cr was associated with worsened survival in patients with GFR <45 …

WebBackground: A blood urea nitrogen (BUN)/creatinine ratio (BCR) >20 (0.081 in international unit) is used to distinguish pre-renal azotemia (PRA) and acute tubular necrosis (ATN). However, there is little evidence that BCR can distinguish between these two conditions and/or is clinically useful. Methods: We conducted a retrospective study using a large … Web3 rows · We may look at the BUN / Creatinine ratio to help determine the cause of renal failure. The ... 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. Prerenal azotemia can be caused by direct intravascular fluid loss (eg, due to … ebay beaded necklaces
