Validity of gestational age estimates by last menstrual period and neonatal examination compared to ultrasound in Vietnam.

ABSTRACT:

Background

Accurate estimation of gestational age is important for both clinical and public health purposes. Estimates of gestational age using fetal ultrasound measurements are considered most accurate but are frequently unavailable in low- and middle-income countries.
