    en.wikipedia.org/wiki/Urea-to-creatinine_ratio

    In medicine, the urea-to-creatinine ratio (UCR [1]), known in the United States as BUN-to-creatinine ratio, is the ratio of the blood levels of urea (mmol/L) and creatinine (Cr) (μmol/L). BUN only reflects the nitrogen content of urea (MW 28) and urea measurement reflects the whole of the molecule (MW 60), urea is just over twice BUN (60/28 ...

    UUN is determined from 24-hour urine collection. Along with UUN, values for BUN, protein content of diet, enteral or parenteral nutrition, and notable outputs other than urine (gastric residual, fistula output, drainages) are needed to calculate nitrogen balance. Nitrogen Balance = Protein intake/6.25- (UN + 4*) * For average loss via sweat and ...

    The original MDRD used six variables with the additional variables being the blood urea nitrogen and albumin levels. [24] The equations have been validated in patients with chronic kidney disease; however, both versions underestimate the GFR in healthy patients with GFRs over 60 mL/min. [ 32 ] [ 33 ] The equations have not been validated in ...
