The creatinine clearance for this patient is 100 mL/min.

The creatinine clearance for this patient is 100 mL/min.

Creatinine clearance values are calculated using the following equation:

Creatinine Clearance (mL / min) = (Urine Creatinine / Serum Creatinine) x Urine Volume (mL) / [ time (hr) x 60 ]

For this patient Creatinine clearance (mL/min)= (120/1.5) x (1800 / [24 x 60])

80 x 1800/1440, which is 80 x 1.25, or 100 mL/min

A 45-year-old male of average height and weight had a serum creatinine of 1.5 mg/dL and urine creatinine was 120 mg/dL; the total volume of urine collected over a 24-hour period was 1,800 mL. Calculate the creatinine clearance for this patient in mL/min.
