How this service works
Gomez 2016 Step-by-Step for febrile infants 90 days and younger (derivation Mintegi 2014). High if ill-appearing, age 21 days or younger, leukocyturia, or PCT >=0.5 ng/mL; else intermediate if CRP >20 mg/L or ANC >10000/uL; else low. Returns risk, low_risk, high_risk, and intermediate_risk. magent does not examine the infant or assay UA, PCT, CRP, or ANC. Not Rochester, Boston, Philadelphia, or PECARN febrile. Not a medical device and not a discharge, admission, LP, or antibiotic order.
Output
Returns a risk category string ('high', 'intermediate', or 'low') along with three boolean flags — low_risk, intermediate_risk, and high_risk — indicating which tier the infant falls into based on the Gomez 2016 Step-by-Step decision tree applied to the provided clinical values.
Example use cases
Febrile neonate 21 days or younger triage
“Use the Step-by-Step algorithm for a 19-day-old febrile infant who is ill-appearing, has leukocyturia, PCT 0.8 ng/mL, CRP 15 mg/L, and ANC 7000/µL — is this baby high risk?”
Borderline intermediate vs low risk infant
“My patient is a 45-day-old febrile infant, well-appearing, no leukocyturia, PCT 0.2 ng/mL, CRP 22 mg/L, ANC 9500/µL — run the Gomez Step-by-Step algorithm and tell me if this is intermediate or low risk.”
Confirming low-risk criteria met
“Can you check if a 60-day-old febrile infant meets low-risk criteria on the Gomez 2016 Step-by-Step? The infant is well-appearing, no leukocyturia, PCT 0.1 ng/mL, CRP 8 mg/L, ANC 6000/µL.”

Endpoint
GEThttps://api.magentlab.com/api/calc/step_by_stepWhen to prefer
Choose this endpoint when you need to apply specifically the Gomez 2016 Step-by-Step algorithm (Mintegi 2014 derivation) for febrile infants 0–90 days old using PCT, CRP, ANC, leukocyturia, age, and appearance — as opposed to Rochester, Boston, Philadelphia, or PECARN criteria, which are different rulesets this endpoint does not implement.
Side effects
- Missing required query parameters (age_days, well_appearing, leukocyturia, pct_ng_ml, crp_mg_l, anc_per_ul) returns a validation error
- age_days outside 0–90 range may be rejected or produce unreliable results since the rule is validated only for infants ≤90 days
- Numeric values outside physiologic ranges (e.g. CRP >500, ANC >100000) may be rejected
- Payment failure (x402) if USDC payment is not properly attached
