Frequently asked questions

What is the Capurro somatic method?

A clinical method for estimating newborn gestational age from 5 somatic features. GA (days) = sum of points + 204.

Capurro somatic vs neurological?

The somatic method uses physical features only — useful when the infant is sedated or unable to be examined neurologically. The neurological method combines somatic and neurological signs.

When should Capurro be performed?

In the first 24 hours of life. Findings change rapidly after birth.

Accuracy?

The somatic Capurro has been reported within ± 8.4 days of true gestational age in original validation studies.
