How this service works
ACR/EULAR 2015 gout classification (Neogi). MSU crystals classify without score ≥8; else score ≥8 (max 23). Pattern 0/1/2, characteristics 0–3, time course 0/1/2, tophus 4, urate −4 to 4, MSU-negative −2, imaging 4+4. Not a diagnosis. Not Janssens 2010. magent does not examine joints or polarizing microscopy.
Output
Returns the total ACR/EULAR 2015 gout classification score (maximum 23 points) along with a classification determination: patients with confirmed MSU crystals classify regardless of score, while others classify if score ≥8. The response includes the numeric total and likely a per-domain breakdown of points contributed by pattern, characteristics, time course, tophus, synovial fluid, and imaging findings.
Example use cases
Rheumatology clinic gout classification
“I have a patient with a swollen 1st MTP joint, two prior typical episodes that resolved within 14 days, no tophus, synovial fluid not done, and urate deposition visible on ultrasound but no erosion — run the ACR/EULAR 2015 gout classification score for me. Entry criterion is met, no MSU crystals confirmed, pattern is mtp1, characteristics score is 2, time course is recurrent.”
ED patient with ankle arthritis workup
“Can you calculate the Neogi 2015 gout classification score for an ED patient? Entry criterion met, no MSU crystals, joint pattern is ankle/midfoot only, characteristics score is 1, one typical episode, no tophus, synovial fluid was tested and MSU-negative, no imaging done for urate or erosion.”
Research study gout case ascertainment
“I need to classify a study participant for gout using the ACR/EULAR 2015 criteria: entry criterion met, no sufficient MSU crystals, pattern is other joints, characteristics score 0, no typical episodes, no tophus, synovial fluid not done, no imaging urate deposition, no imaging erosion — what score do they get and do they classify as gout?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/acr_eular_goutWhen to prefer
Use this endpoint when you need a standardized, reproducible ACR/EULAR 2015 gout classification score based on Neogi criteria, particularly when you have structured clinical data (joint pattern, episode time course, imaging results, tophus, synovial fluid) already coded. Prefer this over manual scoring when building clinical decision support tools, research pipelines, or EHR integrations that need consistent gout case ascertainment. Note this is not the Janssens 2010 rule and is not a diagnostic tool — it is specifically the 2015 ACR/EULAR classification standard.
Side effects
- Missing required query parameters (entry_criterion, sufficient_msu, pattern, characteristics, time_course, tophus, synovial, imaging_urate, imaging_erosion) returns a 400 error
- Invalid enum value for pattern, synovial, time_course, or imaging fields returns a validation error
- Boolean field tophus passed as string rather than boolean may cause a parse error
- Calling when entry criterion is not met is clinically invalid — the score should only be applied when at least one joint has been inflamed
- Payment not included or insufficient USDC results in 402 Payment Required
