Sneak peek gender test4/24/2023 Your sample is mailed to SneakPeek Labs via Priority Mail Express (aka“overnight mail”). SneakPeek Clinical is a non-invasive prenatal test (NIPT), and it’s safe for both mom and baby. SneakPeek is a DNA-based test, so hormones do not impact results. Do hormone disorders such as PCOS affect my results? For fraternal twins (or more!), finding male DNA will confirm at least one baby is a boy, but cannot distinguish if the second is a boy or girl. If no male DNA is found, then both babies are girls. In the case of identical twins, if male DNA is found, then both babies are boys. Can SneakPeek determine fetal sex for each one? Will that skew my results?Ĭlinical studies have shown that fetal DNA clears from mom’s bloodstream between a few hours to 2 days after birth. This blinded study showed that SneakPeek Early Gender Test is highly accurate for fetal sex determination in early pregnancy.įrequently Asked Questions I’ve previously had a boy. SneakPeek accuracy, sensitivity and specificity were each 100% for fetal sex identification. Fetal sex for all samples was unknown prior to genetic testing and was confirmed via sonographic evaluation at the conclusion of the study. Assay precision data showed minimal variation and high reproducibility of results. SneakPeek correctly identified fetal sex in all samples. 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.
