====== Calculated Creatinine Clearance ======

==== For MALES ====

**SI units** \\
Creatinine clearance (mL/min) = 1.23 * Weight (kg) * (140 - Age (y)) / Creatinine (micromol/L)

**Mass units** \\
Creatinine clearance (mL/min) = Weight (kg) * (140 - Age (y)) / Creatinine (mg/dL) * 72

==== For FEMALES ====

  * multiply above by 0.85

==== Validity ====

Valid for ages 18 - 92 years.

==== Normal values ====

Normal values are 120 (males) or 95 (females) +/- 20 mL/minute.
