Gestational age and maternal weight effects on fetal cell-free DNA in maternal plasma.

Prenatal diagnosis - 1 Jul 2013

Abstract excerpt

OBJECTIVE: To determine the effects of gestational age and maternal weight on percent fetal cell-free DNA (cfDNA) in maternal plasma and the change in fetal cfDNA amounts within the same patient over time. METHODS: The cfDNA was extracted from maternal plasma from 22 384 singleton pregnancies of at least 10 weeks gestation undergoing the Harmony(TM) Prenatal Test. The Harmony Prenatal Test determined fetal...
