What it computes

Compute the Le Gal 2006 revised Geneva score for suspected pulmonary embolism in the emergency department from age, heart rate, and six caller-assigned findings.

When to use

When an agent needs the published original revised Geneva arithmetic (not simplified Geneva, not Wells) from caller-assigned findings.

When not to use

Not a diagnosis of pulmonary embolism. magent does not diagnose PE.
This tool is the original revised Geneva score (Le Gal 2006), not simplified Geneva (Klok 2008) and not Wells.
Age 65 does not score; only age older than 65 years scores 1.
Pain on deep-vein palpation and unilateral edema is a single AND item (4 points), not two separate findings.
Heart rate 75-94 scores 3; 95 or higher scores 5; never both. The caller assigns findings; magent does not examine the patient.

Formula

revised Geneva = age>65 (1) + previous_dvt_or_pe (3) + surgery_or_fracture_within_1_month (2) + active_malignancy (2) + unilateral_lower_limb_pain (3) + hemoptysis (2) + heart_rate_75_94 (3) or heart_rate_ge_95 (5) + pain_on_deep_vein_palpation_and_unilateral_edema (4); max 22; bands 0-3, 4-10, 11-22

Parameters

Name	Type	Required	Description
`age`	integer	required	Age in years (18-120). Scores 1 when age >65; 65 does not score.
`previous_dvt_or_pe`	boolean	required	Previous DVT or PE as assigned by the caller. true or false. 3 points if true.
`surgery_or_fracture_within_1_month`	boolean	required	Surgery under general anesthesia or lower-limb fracture within 1 month (one combined flag). true or false. 2 points if true.
`active_malignancy`	boolean	required	Solid or hematologic malignancy currently active or considered cured <1 year (caller-applied). true or false. 2 points if true.
`unilateral_lower_limb_pain`	boolean	required	Unilateral lower-limb pain. true or false. 3 points if true.
`hemoptysis`	boolean	required	Hemoptysis. true or false. 2 points if true.
`heart_rate_bpm`	integer	required	Heart rate in beats per minute (integer 30-220). Scores 3 when 75-94 inclusive, 5 when ≥95, and 0 when ≤74. Never both 3 and 5.
`pain_on_deep_vein_palpation_and_unilateral_edema`	boolean	required	Pain on deep-vein palpation AND unilateral edema as one combined flag. true or false. 4 points if true.

Bulk (POST)

POST the same path with a JSON items array. Price is n times the GET unit. Invalid items return HTTP 400 before settlement.

POST /api/calc/revised_geneva Max 25 unit_amount * n PREVIEW

1 to 25 items. Each item uses the same keys as the GET query parameters.
The first invalid item fails the whole request (index in the 400 JSON). You are not charged.
HTTP 200 is {count, path, items}. Each items[i] is the GET 200 body for that row.
Catalog misses (empty matches, found=false) stay paid 200s inside that slot.
x402 resource URL is this path plus n and body_sha256. Browsers that prefer text/html get the same paywall as GET; Pay retries POST with the same items.

Payment

Required query parameters must be present and valid. Invalid params return HTTP 400 JSON before settlement. magent does not charge. Fix the params, then request a new 402 quote for that complete URL. Catalog misses (empty matches, found=false) are valid paid 200s. Unpaid valid requests return HTTP 402 with a base64 PAYMENT-REQUIRED header. HTTP 503 is not a new quote: retry the same PAYMENT-SIGNATURE. Full handshake and shared payment errors: Payments. Stdio MCP: /docs/mcp.

Guarantees

Invalid query parameters return HTTP 400 before settlement. You are not charged.
Settlement finishes before the tool executes (paymentFlow upfront). Uncertain or failed settlement fails closed (HTTP 503). Retry the same PAYMENT-SIGNATURE.
HTTP 402 is unpaid only. Do not sign a second authorization because of a 503.
Execution is timeout-bounded and concurrency-capped.
Calculator inputs are stored encrypted for allowlisted operators (Magent Console). They are not in public logs, SSH lookups, catalog, or rollups. Request logs store path without query.
