How to calculate egfr formula
WebIn the eGFR test, the rate is not measured directly. Instead, it is estimated by measuring another substance in the blood. Most often, creatinine is measured, and then special formulas calculate eGFR based on the level of creatinine in the blood. However, eGFR is not a perfect test, and several factors can affect its accuracy. Most eGFR tests are WebGFR in mL/min per 1.73 m 2 = 175 x SerumCr-1.154 x age-0.203 x 1.212 (if patient is black) x 0.742 (if female).
