SneakPeek® Clinical Early DNA Test


SneakPeek® Clinical

There's nothing more exciting than bringing a new life into the world. One thing that's on almost every pregnant woman's mind is the age-old question - is it a boy or is it a girl? Now you don't have to wait months to find out.

How Does SneakPeek® Clinical Work?

While every person has their own DNA in their bloodstream, a pregnant woman's bloodstream also contains DNA from her unborn child. SneakPeek® looks for male chromosomes in a small sample of mom's blood. If male chromosomes are found, that means the baby is a boy. If none are found, the baby is a girl. SneakPeek® is 99.9% accurate at 6 weeks into pregnancy.

What Is the Sneakpeek® Clinical Process?

At SneakPeek® Labs, a test process called non-invasive prenatal testing (NIPT) is used to analyze cell-free fetal DNA. Starting with a small sample of blood from mom, plasma is separated from whole blood by centrifuge, and extracted cell-free fetal DNA (cffDNA) is analyzed for Y chromosomes, which are found only in males. The SneakPeek® test is sensitive enough to find even a single Y chromosome, giving you confidence in your results.​

PRO TIP: Before booking your appointment, use the SneakPeek Test Eligibility Calculator to ensure you are far enough along (at least seven weeks) on the date your sample is collected.

Large scale follow-up research study: SneakPeek® Early Gender DNA Test 99.9% accurate for fetal sex by live-birth confirmation

International Journal of Pregnancy & Child Birth – December 29, 2020

Early fetal sex determination has become more prevalent among parents interested in planning for their unborn child. Current advances in non-invasive prenatal testing (NIPT) have facilitated this desire with safe and efficient methods such as the SneakPeek® Early Gender DNA Test (“SneakPeek”).


Motivations behind Early Fetal Sex Determination

Clinics in Mother and Child Health – October 14, 2020

There are many momentous events that accompany the journey of childbirth, one of which is the discovery of the fetus’s sex. What most expecting families are unaware of is that in addition to the traditional approaches, there exists newer developed technologies that allow for an earlier determination of the fetus’s sex.


Reported Benefits of Early Fetal Sex Determination

International Journal of Pregnancy & Child Birth – June 3, 2020

In order to assess the perceived benefits of early fetal sex determination, Gateway Genomics constructed a study in which postpartum women provided insight into the effect of the early gender test on their pregnancy journey. Results from the survey confirm that early fetal sex determination does confer various benefits to the childbearing process.
