About Bones

What this tool does

Medical reference tools calculate drug dosages by body weight, IV drip rates, creatinine clearance, anion gap, body surface area (BSA), ideal body weight, and pediatric weight-based dosing. These are for reference and educational purposes only.

Why use this tool

Healthcare students and professionals need quick access to clinical formulas during study and practice. Having a validated calculator for Cockcroft-Gault, Mosteller BSA, or IV rate saves time and reduces arithmetic errors.

How it works

Each calculator implements a published clinical formula. Inputs are validated against physiological ranges. Results include the formula used and references, so users can verify the math independently.

Pro tip

These calculators are for reference only and must not replace clinical judgment. Always verify dosing against current prescribing information and institutional protocols before administering any medication.
