The laboratory received a 24-hour urine collection from a 26-year old male (body surface area = 2.34m2), and the total urine collection volume measured 800 mL in 24 hours. After creatinine determinations were performed by the alkaline picrate method, interpret the result. Plasma creatinine: 1.2 mg/dL Urine creatinine: 150 mg/dL

b. The creatinine clearance of the patient is below the reference range.

 

c. The creatinine clearance of the patient is within the reference range.

 

d. The creatinine clearance of the patient is borderline high.
