Breakthrough Publication Shows Gateway Genomics SneakPeek Early Gender DNA Blood Test Identifies Fetal Sex at 8 Weeks into Pregnancy with 99.1% Accuracy

SneakPeek lets parents learn their baby’s gender earlier than any other available method, weeks earlier than non-invasive parental tests (NIPTs) and months earlier than standard anatomy scan ultrasounds.

Gateway Genomics, a leading developer of genomic tests that give families insight into their future children, announces a new publication titled, “Accurate Fetal Sex Determination from Maternal Blood at 8 Weeks Gestation” in the International Journal of Pregnancy & Child Birth. In the study, DNA blood samples were collected from 108 women at an average gestational age of 8 weeks. Cell-free fetal DNA (cffDNA) was extracted and run through the SneakPeek test process, which looks for male chromosomes. If male chromosomes were detected in the fetal DNA found in mom’s blood, the baby was identified as male. If not, the baby was identified as female. Of 51 male-bearing pregnancies, SneakPeek correctly identified all 51, demonstrating 100% sensitivity for Y-chromosome DNA detection, even at this early stage. Of 57 female-bearing pregnancies, SneakPeek correctly identified 56, leading to a 99.1% accuracy rate for the overall study.

“This new study moves the needle one week earlier than our landmark 2017 paper, which demonstrated 99.6% accuracy at 9 weeks,” says Gateway Genomics CEO, Chris Jacob. “Now moms can take the test at an unprecedented 8 weeks into pregnancy instead of 9 and be confident in their gender results. While the one-week improvement is great for any family, for moms who choose our clinical option, it means a SneakPeek test can be included in her first visit to the physician after learning that she’s pregnant, providing added convenience and ease. Since the gender results are emailed, no second doctor’s visit is needed.”

The SneakPeek Early Gender DNA Test is available in two ways: An at-home version, ordered online, lets women self-collect 7-10 drops of blood and send to SneakPeek Labs for immediate analysis. A clinical version, available through participating locations, lets women have their blood drawn at the facility and sent in to SneakPeek Labs for analysis. Because the test is designed to focus only on fetal sex and return just one answer – male or female, it is extremely specific and accurate, even at just 8 weeks into pregnancy. This allows parents to learn the gender of their baby weeks to months earlier than any other available method.
