Audit one source-selected Cockcroft–Gault equation record with an explicit formula-weight basis, SCr result and documented coefficient—without CKD staging or dose advice.
A quick decision brief for this specific tool
One de-identified current drug-label, clinical-protocol or education record that explicitly specifies Cockcroft–Gault; adult age; named formula-weight basis and kilograms; named SCr result in mg/dL; and the exact documented coefficient with its source
A source-preserving entered-equation eCrCl estimate in mL/min with the numerator, denominator and coefficient application exposed, but no CKD stage, renal-function verdict or dose
Evaluate ((140 − age) × formula weight kg) ÷ (72 × SCr mg/dL) × documented coefficient using only the copied values; the tool does not select the equation, weight basis, coefficient, assay interpretation or decision threshold
Choose your path
Reproduce one explicitly source-selected adult Cockcroft–Gault equation record without choosing a weight basis, diagnosing kidney disease or determining a medication dose.
Preserve the label's exact kidney-function equation, formula-weight basis, SCr units and coefficient before checking a threshold.
Name the de-identified drug-label record and copy each documented arithmetic input and source label without substitution.
Can audit the estimate and its steps while seeing no generated dose, stage or universal renal threshold.
Avoid silently treating an unstable SCr result or a generic kilogram value as an approved dosing basis.
Use the reviewed protocol basis, name the selected weight and SCr records, and enter the protocol's coefficient exactly.
Gets a traceable equation result while renal trajectory, clinical context and medication decisions remain explicit external checks.
Understand numerator, denominator and coefficient behavior without learning false CKD stages or dose rules.
Run de-identified exercises with coefficient 1 and 0.85, varied source-labelled weights and positive SCr values.
Can reproduce arithmetic and recognize that Cockcroft–Gault eCrCl is neither measured CrCl nor a CKD diagnosis.
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.
Tools you might need next
Reproduce de-identified, source-labelled dosing-weight × mg/kg arithmetic and an optional documented mg/mL division without creating or approving a medication order.
Audit one source-labelled same-panel anion gap with an explicit potassium formula and optional fully documented albumin adjustment—without a universal range or diagnosis.
Reproduce one source-labelled albumin-adjustment method for paired total calcium and albumin with explicit units, reference albumin and factor—without an ionized-calcium estimate or diagnosis.
NIDDK notes that FDA does not recommend one universal kidney-function estimating equation. Drug labels may use SCr, measured CrCl or different estimates, so the named current source comes before arithmetic.
Confirm the current source explicitly calls for Cockcroft–GaultEvery variable is copied from the same reviewed equation context. The tool does not infer actual, ideal or adjusted weight, does not infer a coefficient from identity and does not convert SCr units.
eCrCl = ((140 − age) × formula weight kg) ÷ (72 × SCr mg/dL) × coefficientSerum creatinine is affected by non-GFR factors and estimates may be inaccurate in important body-size or muscle-mass settings. Prescriber and pharmacist review owns renal trajectory, dialysis context, drug exposure evidence and every decision threshold.
Entered estimate ≠ measured CrCl ≠ eGFR ≠ CKD stage ≠ drug doseUpdated: August 2026
Name the exact label section, copy its selected formula-weight basis and coefficient, and audit the arithmetic. Compare with the label only after patient, SCr stability and units are independently reconciled.
Record the protocol-selected weight label exactly. A generic kilogram entry cannot tell whether actual, ideal, adjusted or another basis was intended.
Run separate de-identified records with a documented coefficient of 1 or 0.85 to see the arithmetic effect. The calculator does not assign either coefficient to a person.
Reproduce only the Cockcroft–Gault arithmetic explicitly required by one current drug label, reviewed clinical protocol or education record. Name the de-identified equation source, selected formula-weight basis, SCr result and coefficient instead of letting the calculator choose them. The output is not measured creatinine clearance, eGFR, CKD staging, a stable-renal-function finding or a medication dose.
