In the formula for urea clearance, C = U x V/P, what does U stands for:
Urinary concentration in g/24 hour
Urinary concentration in mg/ml
Urine osmolarity
Urine volume per minute
Ans: B. Urinary concentration in mg/ml(Ref: Ganong 25/p p676. 21/c p678)In given formula for measuring GFR:C = Clearance of the substanceU = Urinary concentration of the substance in mg/mlP = Plasma concentration of the substance in mg/mlV = Volume of urine
