How this service works
Stanghellini 2016 Rome IV B1 FD. rome_iv_fd is true iff last-3-months criteria with 6-month onset, no structural disease likely to explain symptoms, and PDS (B1a) and/or EPS (B1b). pds iff fullness and/or early satiation >=3 days/week. eps iff epigastric pain and/or burning >=1 day/week. Overlap allowed. Caller assigns six flags. magent does not examine the patient. Not a diagnosis, not Rome III dyspepsia, not Rome IV IBS.
Output
Returns boolean flags indicating whether the patient meets overall Rome IV FD criteria (rome_iv_fd), and whether they qualify for the PDS subtype (postprandial distress syndrome based on fullness and/or early satiation ≥3 days/week) and/or EPS subtype (epigastric pain syndrome based on pain and/or burning ≥1 day/week). Overlap between subtypes is permitted per Rome IV.
Example use cases
GI clinic FD subtype triage
“I need to classify a patient for functional dyspepsia under Rome IV: criteria met for last 3 months with 6-month onset, no structural disease on endoscopy, postprandial fullness is present 4 days a week, early satiation 3 days a week, but no epigastric pain or burning — do they have FD and is it PDS or EPS?”
Clinical research eligibility screening
“We're screening patients for a functional dyspepsia trial — this subject has 6-month symptom onset, criteria confirmed for 3 months, structural disease ruled out, epigastric pain 2 days a week, epigastric burning 1 day a week, no fullness or early satiation. Can you run the Rome IV FD check and tell us if they qualify and under which subtype?”
EHR documentation automation
“For this patient's chart, confirm Rome IV FD status: symptoms ongoing 3 months, onset 7 months ago, no structural disease found, no postprandial fullness, no early satiation, bothersome epigastric burning on 3 days per week, no epigastric pain — please calculate if they meet Rome IV functional dyspepsia criteria.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/rome_iv_fdWhen to prefer
Use this endpoint when you need a fast, rule-based Rome IV B1 Functional Dyspepsia classification from pre-assessed clinical flags. It implements the exact Stanghellini 2016 criteria and distinguishes PDS from EPS subtypes, which Rome III did not. Prefer this over manual lookup when embedding clinical scoring into a workflow, EHR pipeline, or research screening tool. Not suitable for diagnosing patients directly — a clinician must assign the input flags.
Side effects
- Missing any of the six required boolean query parameters returns a validation error
- Non-boolean values for any flag result in a schema error
- Network or server errors return standard HTTP error codes
- Caller misassignment of flags will produce clinically incorrect results — the API trusts caller input without validation
