Mean Creatinine Clearance (mL/min/1.73 m2)a
| Age (yr) | Men | Women |
|---|---|---|
| 20–30 | 90–140 or 0.8–1.3 mL/sec/m2 | 72–110 or 0.69–1.06 mL/sec/m2 |
| 30–40 | 59–137 or 0.5–1.3 mL/sec/m2 | 71–121 or 0.68–1.17 mL/sec/m2 |
a Values slowly increase to adult levels and then slowly decrease each decade thereafter (the decrease per decade is approximately 6.5 mL/min/1.73 m2 or 0.06 mL/sec/m2).
