Work out meld score instantly with clear inputs, formula shown and shareable results.
Applies the original MELD equation to bilirubin, INR and creatinine, with the standard flooring at 1.0 and creatinine capped at 4 mg/dL.
MELD
MELD = 3.78 ln(bilirubin) + 11.2 ln(INR) + 9.57 ln(creatinine) + 6.43, values below 1 set to 1, creatinine capped at 4, score bounded 6-40
