Accurate Fetal Sex Determination from Maternal Blood at 8 Weeks Gestation

Journal of Pregnancy & Child Health - July 8, 2019

Prior studies have shown that SneakPeek® Early Gender Test can accurately determine fetal sex as early as 9 weeks gestation using a qPCR-based assay. The purpose of this study was to evaluate the clinical performance of SneakPeek® for noninvasive prenatal testing (NIPT) to determine fetal sex at an earlier time point: 8 weeks gestation.


Self-Collection of Maternal Blood for Fetal Sex Determination Using Cell-Free DNA

Journal of Pregnancy & Child Health - March 1, 2019

SneakPeek® Early Gender Test (Gateway Genomics) is a qPCR-based assay that utilizes a microvolume of maternal plasma to determine the fetal sex as early as 9 weeks gestation. In this study, we aimed to evaluate the accuracy of SneakPeek Early Gender Test for fetal sex determination in self-collected maternal blood samples.


Early Fetal Sex Determination using Cell-Free DNA in Micro-Volume of Maternal Plasma

Journal of Pregnancy & Child Health - December 2, 2017

A qPCR-based assay, SneakPeek® Early Gender Test (Gateway Genomics), has been developed to determine fetal sex as early as 9 weeks gestation using a micro-volume of maternal plasma. The purpose of this study was to assess the clinical performance of SneakPeek for noninvasive prenatal testing (NIPT) of fetal sex.
