Y-chromosome DNA was detected in all samples from women carrying a male fetus. Sixty maternal plasma samples were tested twice, on different days, to assess the precision of SneakPeek.Ĭell-free DNA was detected in all maternal blood samples. An autosomal control gene was used to measure total cell-free DNA (maternal and fetal cfDNA). The clinical DNA testing is different from the home kits.Ĭirculating 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. There were no cases of male DNA contamination with the clinical DNA testing. 30 of 30 were correctly identified as male and 45 of 45 were correctly identified as female. DNA blood samples were collected from 75 women gestational age and a second sample was collected at 8 weeks gestation to confirm the 7 week test result. A new large scale study was run from May to August 2021 to determine the accuracy and sensitivity of the early gender test at 7 weeks. A multicenter-blinded study was conducted at four ultrasound clinics with maternal blood samples collected from pregnant women between 9 and 35 weeks of gestation. The purpose of this study was to assess the clinical performance of SneakPeek® Early Gender Test (Gateway Genomics) for noninvasive prenatal testing (NIPT) of fetal sex. Multicenter Blinded Study Of SneekPeek Was Conducted At Four Ultrasound Clinics In 2015. If it is detected then the baby’s gender is male and if it is not detected then the baby’s gender is female. Our PCR technology has the ability to detect the presence or absence of male Y chromosome in the blood sample provided starting at 7 weeks into pregnancy. ![]() ![]() SneakPeek® utilizes the natural process of shared fetal DNA circulating inside the mother’s bloodstream.
