Q

If an EDD wasn’t noted, the age of the baby can be estimated using Dubowitz Scoring. What is it?

A

Uses external physical and neurological features to give a score which then gives a two week window of estimation

Neuromuscular - posture, popliteal angle, heel to ear
Physical - skin, lanugo hair,genitals, eye/ear
