How Calculators Work
How Calculators Work
Every Pharazi.ai calculator follows the same pattern: Input → Calculate → Interpret.
The Three Phases
1
Input Parameters
Each calculator shows clearly labeled fields with:
- Parameter name and description
- Units (automatically converted)
- Default values based on population averages
- Validation — fields turn red if values are out of range
❗
Important
Default values are population means. Always enter patient-specific data when available for clinical decisions.
2
Calculation Engine
When you click Calculate, the engine:
- Validates all inputs against clinical ranges
- Runs the pharmacokinetic equations
- Generates derived parameters (when applicable)
- Renders visual outputs (charts, gauges, timelines)
ℹ️
Note
All calculations run client-side in your browser — your data never leaves your device.

AI Interpretation
After the calculation, our AI provides:
- Clinical context — What the result means in practice
- Risk flags — Warnings for values outside therapeutic ranges
- Recommendations — Suggested next steps or adjustments
- References — Links to relevant literature
Understanding Result Cards
Each result card displays:
| Element | Description |
|---|---|
| Value | The calculated number with appropriate precision |
| Unit | SI or conventional units |
| Range bar | Visual indicator showing where the value falls |
| Status | Normal, Low, High, or Critical |
| AI text | Plain-language interpretation |
Accuracy and Limitations
🛡️
Caution
Results are for educational and research purposes. Always verify with clinical judgment and established protocols.
- Calculations use peer-reviewed equations from standard PK textbooks
- Every calculator page includes the exact formula, derivation, references, and worked examples
- Click "Formula and References" below any calculator to see the math
