Background: The SneakPeek® Early Gender Test was previously shown to be 99.9% accurate in determining fetal sex
as early as seven weeks of gestation. To our knowledge, no prior study has shown fetal sex identification from
maternal plasma earlier than seven weeks of gestation with high accuracy. The SneakPeek assay was further optimized
to enable fetal sex identification at earlier gestations and its performance characteristics were determined at 6-weeks’
gestation.
Method: Between May and September 2021, 156 pregnant women were recruited from 12 clinics in the
United States. After excluding participants that reported miscarriage during the study, reported twin/triplet
pregnancy, or miscalculated gestational age at the time of the initial sample collection, 115 individuals completed
the trial in its entirety. Thr.. View more»
