How this service works
Jin 2018 ED model for early diagnosis of acute pancreatitis when lipase is at least 3x ULN. Integer points: prior episodes 0/1/2/3/4, cholelithiasis +2, abdominal surgery in 2 months -2, epigastric pain +2, worsening pain +1, pain duration >=5 days -1, severity mild 0 / moderate +2 / severe +3, lipase fold +0/+1/+2. Score max 14; jin2018_high_ppv if score>=8; jin2024_accuracy_cut if score>=6. Not a diagnosis. Not an imaging order. Not Ranson, BISAP, or Glasgow-Imrie.
Output
Returns the computed Jin 2018 integer total score (max 14) summed from all eight clinical parameters, plus boolean flags: jin2018_high_ppv (true if score ≥8) and jin2024_accuracy_cut (true if score ≥6). Returns an invalid_ap_prediction flag if lipase fold is below 3× ULN. Does not provide a diagnosis, imaging order, or treatment recommendation.
Example use cases
ED triage for first-time AP suspect
“Score this ED patient for early acute pancreatitis using Jin 2018 — they have no prior AP episodes, no cholelithiasis, no recent abdominal surgery, epigastric pain present, worsening pain yes, pain under 5 days, pain is severe (7-10/10), and lipase is 22 times the upper limit of normal.”
Recurrent pancreatitis risk stratification
“Calculate the Jin 2018 AP prediction score for a patient with 3 prior pancreatitis episodes, cholelithiasis confirmed, no abdominal surgery in the past 2 months, epigastric pain yes, pain not worsening, duration less than 5 days, mild pain (0-3/10), lipase fold of 8 times ULN — tell me if they hit the high-PPV threshold.”
Post-surgical abdominal pain evaluation
“Run the Jin 2018 acute pancreatitis score for someone who had abdominal surgery 6 weeks ago, 2 prior AP episodes, no cholelithiasis, epigastric pain present, worsening pain no, pain lasting 6 days, moderate severity, and lipase at 5 times ULN — I want to know the total score and whether it crosses the accuracy cutoff.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/ap_predictionWhen to prefer
Use this endpoint when you need a structured, reproducible integer score for early acute pancreatitis diagnosis specifically following the Jin 2018 model in patients with serum lipase ≥3× ULN. Prefer this over BISAP (mortality-focused), Ranson (24/48h severity), or Glasgow-Imrie (severity) when the clinical goal is early ED diagnosis confirmation rather than severity stratification or mortality prediction. Choose this when you already have caller-assigned clinical variables and a confirmed lipase fold value and want a score plus threshold flags, not an imaging order or clinical examination.
Side effects
- lipase_uln_fold below 3 returns invalid_ap_prediction — the model population requires confirmed lipase ≥3× ULN
- missing required query parameters return a 4xx error
- out-of-enum values for prior_ap_episodes, pain_severity, or pain_duration_days return validation errors
- network or service errors return 5xx; retry is safe as endpoint is idempotent
- payment failure (x402) if USDC balance is insufficient
