(A) Urinary concentration in gm/24 hours (B) Urine osmolarity (C) Urinary concentration in mg/ml (D) Urine volume per minute
(C) Ans: C. Urinary concentration in mg/ml In the Given Formula:C = Clearance of the substanceU = Urinary concentration of the substance in mg/mlP = Plasma concentration of the substance in mg/mlV = Volume of urine
