How to use

  1. Examine the newborn and select the matching option for each of the 6 features.
  2. Estimated GA in weeks + days updates instantly (sum + 200 days).
  3. Use after the first 24 hours of life for best reliability.

Frequently asked questions

When is the Capurro neurological method preferred?

After the first 24 hours of life, when neurological responses become reliable and somatic features alone may be insufficient.

How is the score interpreted?

GA (days) = sum of points + 200. Convert to weeks + days.

What if the newborn is sedated?

Use the Capurro somatic method instead, since neurological responses will be unreliable.

How accurate is this method?

Generally within ± 7 days of the true gestational age in healthy term newborns.
