Gadolinium Dose accuracy and testing

This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.

Formula source

**Total Dose (mmol)** = Weight (kg) × 0.1 mmol/kg **Volume (mL)** = Total Dose / Concentration (mmol/mL)

Test cases

Default input regression check

Generated from the checked-in default inputs and calculate function.

Inputs

Patient Weight: 75 kg
Concentration: 0.5 mmol/mL (Standard)

Expected outputs

Injection Volume: 15 mL
Total Dose: 7.5 mmol

Known limitations

This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
Use the result as a planning estimate unless the calculator page states a stricter purpose.

Assumptions

The calculation uses a standard 0.1 mmol/kg dose and does not model every agent-specific indication or reduced-dose protocol.
Renal function screening, labeling restrictions, and institutional safety checks remain essential before administration.
This tool supports dose preparation and should not be treated as an authorization to give contrast.

Unit handling

Patient Weight accepts values in kg.
Concentration accepts one of the configured options.
Injection Volume is displayed in mL.
Total Dose is displayed in mmol.

Rounding rules

Number displays use up to 2 decimal places in the calculator UI.
