How It Works?
The clinical 7+ Week Gender Blood Test utilizes the natural process of shared fetal DNA circulating inside the mother’s bloodstream. Our PCR technology has the ability to detect the presence or absence of the Y chromosome in the blood sample provided to us, starting at just 7 weeks into pregnancy.
The presence of the Y chromosome indicates it’s a boy, its absence means it’s a girl.

- A Multicenter-blinded study was conducted at 4 ultrasound clinics in 2015. The purpose of this study was to assess the clinical performance of the SneakPeek® Early Gender Test (Gateway Genomics) for noninvasive prenatal testing (NIPT) for fetal gender. The study was conducted at these clinics with maternal blood samples collected from pregnant women between 9 to 35 weeks of gestation. Circulating cell-free DNA was isolated from a micro-volume of maternal plasma and real-time quantitative PCR was performed to detect fetal DNA using a multi-copy sequence on the Y chromosome. An autosomal control gene was used to measure total cell-free DNA (maternal and fetal cfDNA). Sixty maternal plasma samples were tested twice, on different days, to assess the precision of SneakPeek.
- Cell-free DNA was detected in all maternal blood samples.
- Y chromosome DNA was detected in all samples from women carrying a male fetus.
- SneakPeek correctly identified fetal gender in all samples.
- Assay precision data showed minimal variation and high productivity of results.
- Fetal gender for all samples was unknown prior to genetic testing and was confirmed via sonographic evaluation at the conclusion of the study. Sneak Peek accuracy, sensitivity, and specificity were each 100% for fetal sex identification. This blinded study showed that SneakPeek Early Gender Test is highly accurate for fetal gender determination in early pregnancy.
