Unformatted text preview: P X GFR = U X V * P = plasma concentration of inulin, in mg/mL * GFR = glomerular filtration rate of plasma, in mL/min * U = urine concentration of inulin, in mg/mL * V = rate of urine production, in mL/min * Solving the equation for GFR will give: GFR = (U X V)/P Creatinine * Creatinine is a by product of muscle metabolism * Serum creatinine level and "creatinine clearance" are different ways of determining kidney function. * The amount produced is relatively stable in a given person and is dependent on muscle mass * The creatinine level in the serum is therefore determined by the rate it is being removed, which is roughly a measure of kidney function. * If kidney function falls (say a kidney is removed to donate to a relative), the creatinine level will rise. * Normal is about 1 for an average adult....
