Equations for estimating GFR
| Rule | 66.8 × cystatin C−1.30 |
|---|---|
| MDRD | 175 × Scr−1.154 × age−0.203 × 0.742 [if female] × 1.272[if black] |
| CKD-EPI | 141 × min(Scr/k, 1)<101> × max(Scr/k, 1)−1.209 × 0.993age × 1.018[if female] × 1.159[if black] |
Scr is serum creatinine, k is 0.7 for females and 0.9 for males, α is −0.329 for females and −0.411 for males, min indicates the minimum of Scr/k, and max indicates the maximum of Scr/k.
