What is Sneakpeek Clinical?

SneakPeek Clinical is an early gender DNA detection test offered to women starting at 9 weeks into pregnancy.

The genetic test gives you the first step to connect with your baby before you are able to see the exciting clear images from your ultrasound scans. The full service includes an on-site phlebotomy expert that draws a blood sample in the comfort of our office, and then returns the sample to SneakPeek Labs for processing.

The laboratories offer the fastest turnaround times in the industry, with a choice of receiving your result the same day the sample reaches the SneakPeek Lab, for a small additional fee!

How does SneakPeek® work?

SneakPeek 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 male Y chromosome in the blood sample provided starting at 9 weeks into pregnancy. If it is detected then the baby’s gender is male and if it is not detected then the baby’s gender is female.

SneakPeek Clinical Accuracy

Multicenter Blinded Study of SneakPeek® Early Gender Test at four ultrasound clinics in 2015:

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. 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. 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 sex in all samples. Assay precision data showed minimal variation and high reproducibility of results. Fetal sex for all samples was unknown prior to genetic testing and was confirmed via sonographic evaluation at the conclusion of the study. SneakPeek 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 sex determination in early pregnancy.
