MELD Calculator
The Model for End-Stage Liver Disease (MELD) score is a crucial tool in hepatology that predicts mortality risk in patients with end-stage liver disease.
This calculator implements three versions of the MELD score:
Original MELD Score
MELD-Na Score (with sodium correction)
MELD 3.0 (latest version with enhanced accuracy)
| Original MELD | : | |
| MELD Score - NA | : | |
