Dubowitz Exam

At this point perform a Dubowitz Examination. This is the method used at our institution to determine the baby's gestational age. This examination evaluates both physical characteristics and neurological characteristics and in the aggregate, estimates the baby's gestational age within 1-2 weeks of the true gestational age.
