Bun creatinine ratio for prerenal
WebThe ratio is predictive of prerenal injury when BUN:Cr exceeds 20 or when urea:Cr exceeds 100. In prerenal injury, urea increases disproportionately to creatinine due to enhanced proximal tubular reabsorption that follows the enhanced transport of … WebApr 2, 2024 · The normal ratio of BUN to creatinine in the blood is between 10 and 20 to 1, more or less, although this “normal” range varies with age and gender. Ratios higher than 20 to 1 or lower than 10 to 1 (with the above caveat) are both indicative of certain kidney problems. High BUN levels (especially in children or when above 30 to 1) can ...
