Educational Cockcroft-Gault creatinine clearance, Mosteller body surface area and absolute eGFR.
No. It is an educational estimate of creatinine clearance in mL/min. It does not output any medication dose. Drug dosing follows the drug-specific Canadian product monograph, local policy and the prescriber or pharmacist.
The tool uses the weight exactly as entered and never switches to ideal or adjusted weight on its own. If you enter height it shows a caution when body mass index is very low or high. Which weight a monograph or local policy expects is a clinical decision.
It is a coefficient of the traditional Cockcroft-Gault equation, derived in a mostly male cohort. It is an equation convention and not a statement about any individual's physiology.
No. Absolute eGFR (mL/min) is the indexed eGFR multiplied by body surface area over 1.73, and Cockcroft-Gault creatinine clearance is a different estimate. Do not substitute one for the other when a monograph names a specific estimate.
These answers are for nursing education and exam practice only and do not provide patient-specific medical advice.
Educational use only. These calculators do not output medication doses and do not replace clinical judgement, local policy or the drug-specific Canadian product monograph.
