In transplantr: Audit and Research Functions for Transplantation. Description Usage Arguments Value Examples. View source: R/unit_conversion.R. Description. A vectorised function to convert urea to blood urea nitrogen (BUN), By default the urea is measured in mmol/l but this can be changed to mg/dl by setting the optional units parameter to "US"
Blood Urea Nitrogen (BUN) Urea nitrogen is the nitrogen portion of urea, a substance formed in the liver through an enzymatic protein breakdown process. Urea is normally freely filtered through the renal glomeruli, with a small amount reabsorbed in the tubules and the remainder excreted in the urine.

The DxC modular chemistry (BUNm) is used to quantitatively determine the concentration of blood urea nitrogen in serum or plasma by means of the enzymatic conductivity rate method. A precise volume of sample is injected into the urease reagent in a reaction cup containing an electrode that responds to changes in solution conductivity.
These are real scientific discoveries about the nature of the human body, which can be invaluable to physicians taking care of patients. Have feedback about this calculator? The MDRD GFR Equation estimates glomerular filtration rate based on creatinine and patient characteristics.
Up to 15 to 25 percent of total crude protein (CP) in cattle and sheep fattening rations. 0.1 to 0.25 pound urea per head per day to cattle. 0.28 to 0.70 pound CP per head per day to cattle. Up to 0.5 to 1.0 percent urea in total air dry beef ration (90 percent dry matter). Current recommendation is 0.7 percent urea. Use this calculator to check if your dialysis session was efficient. Kt/V and Urea Reduction Ratio (URR) are two parameters used to measure the adequacy of dialysis, and consequently dialysis dose More importantly, Bland-Altman plots indicated that a minimal positive bias (mean ± SD) was observed: BUN (0.352 ± 0.289 mmol/L), Cr (2.702 ± 7.683 µmol/L), UA (5.398 ± 7.086 µmol/L). Conclusions: The Vitros5600 and Hitachi7600 systems have good correlation and bias for detecting BUN, Cr, and UA analytes. The two systems have a high wnbIC8s.
