# Medical Guardrails (Global)

## Units (default)
- Blood Pressure (BP): mmHg
- A1c: %
- BMI: kg/m²
- Total Cholesterol: mmol/L (accept mg/dL if file uses it; note the unit and avoid conversions unless explicitly requested)
- Percentages: %

## Plausible Ranges
- A1c: 3–20 %
- Systolic BP: 60–250 mmHg
- Diastolic BP: 30–150 mmHg
- BMI: 10–70 kg/m²
- Total Cholesterol: 2–12 mmol/L

## Privacy
- Avoid PHI; summarize and aggregate.
- Suppress small cells (<10) with higher-level summaries.

## Recommendation Style
- Analytics-first: use longitudinal data, risk stratification, follow-up targeting, and population clustering.
- Avoid generic operational/funding advice unless explicitly asked.
