How this service works
Kim 2021 MELD 3.0 from sex, bilirubin, INR, creatinine, sodium, albumin, and dialysis. meld_3 = round(1.33*(female) + 4.56*ln(bilirubin) + 0.82*(137-Na) - 0.24*(137-Na)*ln(bilirubin) + 9.09*ln(INR) + 11.14*ln(creatinine) + 1.85*(3.5-albumin) - 1.83*(3.5-albumin)*ln(creatinine) + 6). Creatinine 1.0-3.0 (dialysis 3.0); bilirubin and INR floor 1.0; sodium 125-137; albumin 1.5-3.5. Not original MELD or MELD-Na. Not a transplant listing or allocation order.
Output
Returns a rounded MELD 3.0 integer score computed per the Kim 2021 formula, with input clamping applied: creatinine floored at 1.0 and capped at 3.0 (forced to 3.0 if on dialysis), bilirubin and INR floored at 1.0, sodium clamped 125–137, albumin clamped 1.5–3.5. Female sex adds 1.33 points. The score quantifies liver disease severity but is not a transplant listing or allocation order.
Example use cases
Cirrhosis severity assessment in clinic
“I need the MELD 3.0 score for a male patient with bilirubin 5.1 mg/dL, INR 2.1, creatinine 2.3 mg/dL, sodium 129 mmol/L, and albumin 2.2 g/dL — not on dialysis.”
Dialysis patient liver scoring
“Can you compute the Kim 2021 MELD 3.0 for a female patient who has been on dialysis twice this week? Her bilirubin is 4.0 mg/dL, INR is 1.6, sodium is 131 mmol/L, and albumin is 1.9 g/dL.”
Comparing lab trends over time
“My patient's labs just came back — male, bilirubin 1.8 mg/dL, INR 1.2, creatinine 1.1 mg/dL, sodium 136 mmol/L, albumin 3.2 g/dL, no dialysis. What's his updated MELD 3.0 score?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/meld_3When to prefer
Use this endpoint when you specifically need the Kim 2021 MELD 3.0 score — the version that incorporates serum albumin and a sex-specific female term — as distinct from the original MELD or MELD-Na formulas. Prefer it for clinical research, EHR integration, or decision-support tools that require the most current validated MELD variant. Do not use for transplant listing or organ allocation order decisions.
Side effects
- Missing required parameters (sex, INR, sodium, dialysis) return a validation error
- Out-of-range numeric values may be rejected or silently clamped depending on server behavior
- Providing neither albumin_g_dl nor albumin_g_l when albumin is needed may cause an error
- Providing neither bilirubin_mg_dl nor bilirubin_umol_l or neither creatinine unit variant may cause missing-field errors
- Network or payment (x402) failures return 402 or 5xx status codes
