What standard body surface area value is used in creatinine clearance normalization?

Explanation:
The value used to normalize creatinine clearance to a standard body size is 1.73 m^2. This allows clearance measurements to be compared across individuals of different sizes by expressing the result as mL/min per 1.73 m^2. In practice, you adjust the measured clearance by multiplying by 1.73 divided by the patient’s actual body surface area, so CrCl is reported as mL/min/1.73 m^2. The 1.73 m^2 figure comes from historical estimates of average adult body size and remains the conventional reference. Other numbers aren’t used as the standard normalization value.
