The creatinine clearance test is a clinical test to check the kidney function. It is also called a serum creatinine test, is a way for doctors to measure how well your kidneys are working.

**Creatinine Clearanc**e = ((Urine Creatinine × Days Urine Volume) ÷ (Serum Creatinine × 1440)

#### Creatinine Clearance Calculation by Mass

This equation is a simple re-write of the standard formula: Clearance = UV/P.

Where,

• The volume term V is actually best represented as V dot (for flow), with units of mL/min.

• The term UV is the mass of creatinine excreted in one day.

• The constant 0.0144 is a properly scaled version of the number of minutes in one day: 1440

**Equation:**

Creatinine Clearance = (Urine Creatinine Mass at 24 Hours ÷ Serum Creatinine Concentration) ÷ 0.0144

#### Creatinine Clearance Calculation by Cockcroft-Gault Equation

Creatinine Clearance = Sex × ((140 - Age) / (Serum Creatinine)) × (Weight / 72)

- Where, Sex = For Female (0.85) & For Male (1)
