A contemporary amniotic fluid volume chart for the United States: The NICHD Fetal Growth Studies-Singletons.

ABSTRACT:

Background

Amniotic fluid is essential to normal fetal development and is estimated clinically with ultrasound scanning to identify pregnancies that are at risk for poor perinatal outcome.
