Not a medical device. Not a diagnosis, dose, or listing recommendation.

What it computes

Sum the eight Blamey 1984 Glasgow-Imrie factors and return whether severe pancreatitis is predicted (three or more factors).

When to use

When an agent already has the published cutoffs as flags and must not invent a Glasgow-Imrie total, substitute Ranson, or treat the result as a diagnosis.

When not to use

  • Not a medical device and not a diagnosis, ICU order, or treatment recommendation. Blamey 1984 predicts severe pancreatitis when three or more of eight factors are present; magent returns severe_predicted as that published threshold, not a named-patient prognosis.
  • This is the Blamey 1984 eight-factor Glasgow-Imrie system only. Transaminases (AST/ALT) were dropped because they did not predict severity. This is not Ranson 1974 (eleven signs).
  • magent does not convert units or parse raw labs; each cutoff is a caller-assigned boolean.

Formula

Glasgow-Imrie = age_gt_55 + wbc_gt_15 + glucose_gt_10 + urea_gt_16 + pao2_lt_60 + calcium_lt_2 + albumin_lt_32 + ldh_gt_600; each 1 if present; max 8; severe_predicted if score >= 3

Call

Expect HTTP 402 until you retry with PAYMENT-SIGNATURE. Incomplete query params return HTTP 400 before any quote or charge. 

curl -i -H "Accept: application/json" "https://api.magentlab.com/api/calc/glasgow_imrie?age_gt_55=false&wbc_gt_15=false&glucose_gt_10=false&urea_gt_16=false&pao2_lt_60=false&calcium_lt_2=false&albumin_lt_32=false&ldh_gt_600=false"

Parameters

Name Type Required Description
age_gt_55 boolean required Age >55 years (Blamey 1984). true or false.
wbc_gt_15 boolean required WBC >15 ×10^9/L. true or false.
glucose_gt_10 boolean required Glucose >10 mmol/L. true or false.
urea_gt_16 boolean required Urea >16 mmol/L. true or false.
pao2_lt_60 boolean required Arterial PaO2 <60 mm Hg. true or false.
calcium_lt_2 boolean required Calcium <2.0 mmol/L. true or false.
albumin_lt_32 boolean required Albumin <32 g/L. true or false.
ldh_gt_600 boolean required LDH >600 U/L. true or false.

Bulk (POST)

POST the same path with a JSON items array. The first item is the GET unit; each additional item is $0.002. Invalid items return HTTP 400 before settlement.

POST /api/calc/glasgow_imrie Max 25 unit_amount + extra_item_amount * (n - 1) extra $0.002 PREVIEW

  • 1 to 25 items. Each item uses the same keys as the GET query parameters.
  • POST of 1 item costs the same as GET. Lists longer than 25: chunk into multiple POSTs. Extra items still execute; do not pad dummy rows.
  • 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.

Client errors (HTTP 400)

Invalid params return 400 without charge. Shared HTTP 402 and 503 meanings: Payments.

HTTP Code When
400 invalid_flag boolean clinical flags must be true or false Returned before settlement; you are not charged.
400 invalid_items POST body must be a JSON object with only an items array Returned before settlement; you are not charged.
400 invalid_item_count items must be an array of 1 to 25 objects Returned before settlement; you are not charged.
400 invalid_item each items entry must be a JSON object Returned before settlement; you are not charged.

  • Ranson — Sum the eleven Ranson 1974 prognostic signs (five at admission, six during the first 48 hours) and return the published mortality band.
  • BISAP — Compute the Wu 2008 BISAP score for early prediction of mortality in acute pancreatitis from BUN, caller-assigned impaired mental status, caller-assigned SIRS, age, and caller-assigned pleural effusion.

Payment

Unpaid requests return HTTP 402 even if query parameters or POST items are missing or invalid, so CDP and agents can index the path. After a PAYMENT-SIGNATURE, 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

  • HTTP 402 is unpaid, including a missing query. After PAYMENT-SIGNATURE, invalid parameters return HTTP 400 before settlement. You are not charged.
  • exact: settlement finishes before the tool (paymentFlow upfront). batch-settlement: verify/deposit before the tool; chargedCumulativeAmount commits after HTTP 2xx. 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.
