How this service works
Kim 2008 NEJM MELD-Na from creatinine, bilirubin, INR, sodium, and dialysis. Then-current UNOS MELD: dialysis sets creatinine 4.0 else clamp 1.0-4.0; bilirubin and INR floor 1.0. Sodium bound 125-140. MELDNa = MELD - Na - 0.025*MELD*(140-Na) + 140. Not OPTN 2016 MELD-Na (Na 125-137 only if MELD>11). Not Kim 2021 MELD 3.0. Not a transplant listing or allocation order.
Output
Returns the computed MELD-Na score (and likely intermediate MELD) using Kim 2008 rules: dialysis sets creatinine to 4.0; otherwise creatinine clamped 1.0–4.0; bilirubin and INR floored at 1.0; sodium bounded 125–140 for the sodium correction term; MELDNa = MELD − Na − 0.025×MELD×(140−Na) + 140.
Example use cases
Cirrhosis severity scoring in hepatology clinic
“I need the Kim 2008 MELD-Na score for my cirrhotic patient — their creatinine is 1.6 mg/dL, bilirubin 5.2 mg/dL, INR 2.1, sodium 128 mmol/L, and they are not on dialysis.”
MELD-Na for end-stage renal disease patient
“Can you compute the MELD-Na score for a patient who has been on dialysis twice this week, with bilirubin 4.0 mg/dL, INR 1.5, and sodium 135 mmol/L?”
Convert SI units and compute MELD-Na
“Calculate the Kim 2008 MELD-Na for a patient whose creatinine is 185 µmol/L, bilirubin is 68 µmol/L, INR is 1.9, serum sodium is 130 mmol/L, and they haven't had dialysis.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/kim_meldnaWhen to prefer
Use this endpoint when you specifically need the Kim 2008 NEJM MELD-Na formula with then-current UNOS clamping rules (creatinine 1.0–4.0, dialysis→4.0, bilirubin/INR floored at 1.0, sodium bounded 125–140 applied at all MELD values). Choose the sibling OPTN 2016 MELD-Na endpoint if you need the official 2016 OPTN/UNOS formula (sodium adjustment only when MELD>11, sodium bound 125–137). Do not use either for the Kim 2021 MELD 3.0 calculation.
Side effects
- Missing required parameters (inr, sodium_mmol_l, dialysis) returns a validation error
- Neither bilirubin_mg_dl nor bilirubin_umol_l provided causes an error
- Values outside accepted ranges (e.g. sodium outside 110–160) may be rejected or clamped
- Payment failure (x402) if USDC not provided or insufficient
- Network timeout for the API call
