FAQ
What can this site calculate?
It includes creatinine clearance, eGFR, cystatin C-based estimates, UPCR, and UACR tools.
Are CCR and eGFR the same?
No. They use different formulas, units, and clinical contexts; the site explains when each estimate is commonly considered.
Can the result determine a medication dose by itself?
No. Check the current prescribing information and evaluate the patient, laboratory data, and relevant clinical guidance.
Is the calculator suitable for acute kidney injury?
Estimated values are less reliable when renal function is changing rapidly, so clinical assessment and direct measurements are especially important.
Is the site available in English?
The calculator interface and detailed guidance are primarily in Japanese.
