Dialysis clearance equation

K (clearance) multiplied by t (time) is a volume (since mL/min × min = mL, or L/h × h = L), and (K × t) can be thought of as the mL or L of fluid (blood in this case) cleared of urea (or any other solute) during the course of a single treatment. V also is a volume, expressed in mL or L. So the ratio of K × t / V is a so-called "dimensionless ratio" and can be thought of as a multiple of the volume of plasma cleared of urea divided by the distribution volume of urea.

WebThe formula for the calculation of clearance (in this case creatinine) is: CrCl =. U Cr * U Vol. P Cr * T min. For continuous renal replacement therapy, the ultrafiltrate is the "urine." Note that when the Replacement Rate is zero, the Clearance is equivalent to the Ultrafiltration Rate (in mL/min rather than mL/hr). WebRenal clearance of a substance refers to how quickly a particular substance is removed from the plasma by the kidney and excreted in urine. So something with a high renal …

WebThe CKD-EPI formula is the recommended method for estimating GFR and calculating drug doses in most patients with renal impairment. CKD-EPI is adjusted for body surface area (BSA) and utilises serum creatinine, age, sex and race as variables. Clinical laboratories should use the CKD-EPI formula to routinely report eGFR.
