Increased BCR can present in on of the three (3) ways: - Increased plasma urea and normal plasma creatinine. Modest Good in steady state Correlation with Uremic Symptoms. ; If values for cystatin C and/or BUN are not entered, the calculator will generate GFR estimates using the creatinine-based "Bedside Schwartz" equation only (currently considered the best method for estimating GFR in children). We always have to be cautious in interpreting lab values without corresponding "normal" reference ranges, because these ranges can vary from lab to lab; it's also hard to interpret lab work . mg/dL, umol/day, etc.). 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).

So the Urea_mmol to Creatinine_umol = 4.0 / 50.0 = 0.08. So, if a blood test for creatinine shows higher than normal levels, it could mean that you have a kidney problem—even if you feel fine. #5. a BUN/creatinine ratio of 30 or above has a sensitivity of 68.8% for upper GI bleeding and a specificity of 98%- I would assume this only increases with increasing ratio- and this ratio is ~90. The blood in the gut gets digested and this increases the amount of protein and BUN levels [ 12, 13 ]. 1.BUN. A microalbumin creatinine ratio compares the amount of albumin to the amount of creatinine in your urine. The normal value of the BUN-creatinine ratio is different in infants less than 12 months old, where it may be as high as 30:1 and still be normal. In Europe, the whole urea molecule is assayed, whereas in the United . This generally is only helpful if you do not already have chronic renal failure, and are just having an acute episode of renal disease.
