Creatinine clearance Estimated renal function using the Cockcroft-Gault or CKD-EPI (2021) equation. Body surface area BSA from height and weight, using the Mosteller or DuBois formula. Due date Estimated due date and gestational age from the last period or ovulation date.

Clinical reference calculations: estimated kidney function (Cockcroft-Gault and CKD-EPI), body surface area (Mosteller and DuBois) and an estimated due date from the last menstrual period or ovulation date.

These reproduce published clinical formulas exactly and show every substitution. They are decision-support references, not a diagnosis — always confirm with the patient’s chart and a clinician.

Frequently asked questions

Can I use these for a real clinical decision?

They reproduce the published formulas correctly, but a formula is only as good as the values fed into it and the clinical context around them. Cross-check against the patient record and current guidelines, and never adjust a treatment based solely on this page.
