175 * (SCr)^-1.154 * (Age)^-0.203 * (0.742 if female)

The MDRD formula is a standard method for estimating kidney function without a 24-hour urine collection.

Age 50, Male, Creatinine 1.2 -> eGFR ~ 67 mL/min/1.73m².

It measures how well your kidneys filter waste from your blood. A higher number generally means better kidney function.

A normal eGFR is usually 90 or higher. Values below 60 for three months or more may indicate chronic kidney disease.

The MDRD equation is highly validated for patients with known chronic kidney disease (CKD).
