Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability revised-geneva-score-for-pe-le-gal-2006-192bcd3f
```

Example prompt: Run the Revised Geneva Score for a 72-year-old patient with a heart rate of 98 bpm, unilateral left leg pain, and pain on deep-vein palpation with edema — no previous DVT or PE, no active malignancy, no recent surgery or fracture, and no hemoptysis.

## When to prefer this

Use this endpoint when you need the original Revised Geneva Score (Le Gal 2006) with its full 8-variable weighted model for PE pre-test probability in an ED setting. Choose this over Wells criteria when you prefer an objective score without clinical judgment items, and over the Simplified Geneva when the full weighted scoring is clinically indicated or protocol-required.

## Known failure modes

- Missing required query parameters returns an error
- Age outside 18-120 range rejected
- Heart rate outside 30-220 range rejected
- Invalid boolean values for clinical flags cause bad request
- Network timeout on rare high-load scenarios

## How this service works

Revised Geneva score (Le Gal 2006) for suspected PE in the emergency department: age >65 (1), previous DVT or PE (3), surgery or lower-limb fracture within 1 month (2), active malignancy (2), unilateral lower-limb pain (3), hemoptysis (2), heart rate 75-94 (3) or >=95 (5), pain on deep-vein palpation and unilateral edema (4). Max 22. Bands 0-3, 4-10, and 11-22. Not a diagnosis, not simplified Geneva, and not Wells.

## Output

Returns the total Revised Geneva Score (integer 0-22) and the corresponding pre-test probability risk band: low (0-3), intermediate (4-10), or high (11-22), based on the eight weighted clinical criteria from Le Gal et al. 2006.
