How this service works
Sripongpun 2023 steatosis-associated fibrosis estimator (SAFE) from age, BMI (capped at 40 in the equation), diabetes, AST, ALT, globulin in g/dL, and platelets. Deterministic published equation with citation. Rule-out below 0; rule-in above 100. Not a biopsy, fibrosis stage, FIB-4, NAFLD fibrosis score, or BARD. magent does not compute BMI from height and weight.
Output
Returns the numeric SAFE score computed from the Sripongpun 2023 published equation. Scores below 0 indicate rule-out for significant fibrosis; scores above 100 indicate rule-in. The caller-supplied BMI is echoed back; values above 40 are capped at 40 in the formula per the published equation.
Example use cases
Pre-referral liver fibrosis triage
“I have a 47-year-old non-diabetic patient with BMI 29, AST 55 U/L, ALT 72 U/L, globulin 2.8 g/dL, and platelets 210 × 10⁹/L — run the SAFE score so I can decide whether to refer them for further workup.”
Diabetic patient metabolic liver screen
“My patient is 61 years old, has type 2 diabetes, BMI 38, AST 80 U/L, ALT 65 U/L, globulin 3.5 g/dL, and a platelet count of 145 × 10⁹/L — compute their Sripongpun SAFE score to assess fibrosis risk.”
Population health fibrosis risk flagging
“For a 39-year-old patient without diabetes, BMI 26, AST 30 U/L, ALT 25 U/L, globulin 2.4 g/dL, platelets 290 × 10⁹/L — what is their SAFE score and does it rule out significant liver fibrosis?”

Endpoint
GEThttps://api.magentlab.com/api/calc/safeWhen to prefer
Use this endpoint when you need the specific Sripongpun 2023 SAFE (steatosis-associated fibrosis estimator) score. Choose it over FIB-4 or NAFLD fibrosis score endpoints when the clinical protocol or study context specifically calls for the SAFE equation. It is appropriate for adult patients (18+) where all seven input lab values and clinical parameters are available. Do not use this endpoint to obtain FIB-4, APRI, BARD, or biopsy-equivalent fibrosis staging — use the dedicated magent endpoints for those scores instead.
Side effects
- Missing required parameter returns validation error
- BMI outside 10–80 range rejected
- Age outside 18–120 range rejected
- AST or ALT outside 1–10000 range rejected
- Globulin outside 0.5–8.0 range rejected
- Platelets outside 1–2000 range rejected
- Payment failure (x402) if USDC balance insufficient
