What it calculates

The “Child-Pugh Score” calculator computes Child-Pugh in points from 5 parameters: total bilirubin (µmol/L), albumin (g/L), inr, ascites (0 = none, 1 = mild, 2 = moderate/severe), encephalopathy (0 = none, 1 = grade i–ii, 2 = grade iii–iv).

Used by professionals and patients to assess health metrics, dosages, and risks.

Example calculation

With parameters Total bilirubin = 40 µmol/L, Albumin = 30 g/L, INR = 1.5, Ascites (0 = none, 1 = mild, 2 = moderate/severe) = 1, Encephalopathy (0 = none, 1 = grade I–II, 2 = grade III–IV) = 0 the result is 8 points (Severity assessment of liver cirrhosis).

How to use

  1. Enter total bilirubin, albumin, inr, ascites (0 = none, 1 = mild, 2 = moderate/severe) and encephalopathy (0 = none, 1 = grade i–ii, 2 = grade iii–iv) — each field above is adjustable with a slider.
  2. Child-Pugh (points) is calculated automatically as you type.
  3. Check the worked example below to see the formula applied to real numbers.

FAQ

How is BMI calculated?
BMI = weight (kg) / height (m)². Example: 70 kg / (1.75 m)² = 22.9. The WHO normal range is 18.5–24.9; below that is underweight, 25–29.9 is overweight, and 30+ is obese.
Is BMI accurate for everyone?
No. BMI does not distinguish muscle from fat, so athletes may show a high BMI with low body fat. It is also less reliable for teenagers, pregnant people, older adults, and very tall or short individuals.
What are the BMI categories?
Underweight: below 18.5. Normal: 18.5–24.9. Overweight: 25–29.9. Obese class I: 30–34.9; class II: 35–39.9; class III: 40+.
What is a better measure than BMI?
Body fat percentage, waist-to-height ratio (aim for under 0.5), and waist circumference give a clearer picture of health than BMI alone.
