Creatinine Clearance Calculator

Estimate kidney function as creatinine clearance (CrCl) in mL/min using the Cockcroft-Gault equation. Pharmacists and clinicians use it to adjust drug doses in renal impairment.

Kidney Function Calculator (eGFR)

Estimates your glomerular filtration rate (eGFR) using the CKD-EPI equation from serum creatinine, age, sex, and race. Clinicians and patients use it to stage chronic kidney disease and track how well the kidneys are filtering blood.
