Meld Calculator
Result
MELD Score (Liver Disease) Calculate the MELD score (Model for End-Stage Liver Disease) to predict 90-day mortality. — free online calculator.
Formula
- Meld Calculator calculates its result from Cr, Bili, Inr, Na. It uses the formula MELD = 3.78×ln(bili) + 11.2×ln(INR) + 9.57×ln(Cr) + 6.43; MELD-Na = MELD − Na − 0.025×MELD×(140−Na) + 140. Change any input to recalculate the result instantly. This is an informational calculation and is not medical advice.
- The main inputs are Cr, Bili, Inr, Na. Enter them in the units and format shown in the calculator.
- Use the measurement units shown beside each field. The result is an estimate and should be interpreted in context.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Meld
- Cr: 2
- Bili: 3
- Inr: 4
- Na: 5
Using Cr = 2, Bili = 3, Inr = 4, Na = 5, the calculated result is 57.2361591925.
