More about: PELD

What it calculates

The “PELD” calculator computes PELD from 5 parameters: total bilirubin (µmol/L), inr, albumin (g/L), age <1 year at listing (1 = yes), growth failure (< −2 sd) (1 = yes).

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

Example calculation

With parameters Total bilirubin = 171 µmol/L, INR = 1.8, Albumin = 30 g/L, Age <1 year at listing (1 = yes) = 1, Growth failure (< −2 SD) (1 = yes) = 0 the result is 18.8 (The age adjustment is kept until 24 months of age).

How to use

  1. Enter total bilirubin, inr, albumin, age <1 year at listing (1 = yes) and growth failure (< −2 sd) (1 = yes) — each field above is adjustable with a slider.
  2. PELD is calculated automatically as you type.
  3. Check the worked example below to see the formula applied to real numbers.
  4. Copy the result or bookmark this calculator.

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.
