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 phlebotomist that draws a blood sample in the comfort of the ultrasound studio, 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.

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.

How Accurate are the Results?

Under the conditions of the test being performed in a sterile environment via standard venipuncture by a licensed Phlebotomist, the accuracy rate is 100%. SneakPeek performed a blinded multi-center study in 2015 at four independent clinical sites to assess the performance of the Prenatal Gender Test. Venous blood samples were collected from women between 9 and 22 weeks gestation. The Prenatal Gender Test correctly identified fetal sex in all samples. Fetal sex for all samples was unknown prior to genetic testing and was confirmed via ultrasound at the end of the study. The tests yielded 100% accuracy for fetal sex identification.

Where is the DNA Gender Blood Test Performed?

The blood tests are conveniently performed every Thursday from 12PM-1PM with a licensed phlebotomist at Take A Peep 3D & 4D Ultrasound and Baby Boutique. This is a closed blood draw from the vein, providing higher accuracy then a finger prick blood test which has a chance of becoming contaminated.

When Will I Get My Results?

We will ship the test to the lab using USPS Next Day Air. For Standard processing, you will get the results the day after the sample reaches the lab or you may choose to upgrade to FastTrack and get the results the same day the blood sample reaches the lab. (Provided that there are no shipping delays, FastTrack would provide next day results and Standard would provide 2 day results). The results will be sent to an email in which you provide on the consent form the day the sample is taken.

How Much Does it Cost?

SneakPeek Clinical Standard – $129 Clients will receive the results 2 days from their appointment date. SneakPeek Clinical FastTrack – $149 Clients will receive the results the day after their appointment date. Please refer to our Pricing Page for more information. Insurance does not cover the cost, since it is an elective service that is not medically necessary.


What is the DNA & Donuts™ Experience?

DNA & Donuts is a breakfast party for expectant mothers where they can find out the gender of their babies starting at 9 weeks! Our ultrasound studio hosts a unique SneakPeek Clinical social event every Thursday from 12 noon – 1 pm to bring pregnant moms together to share in their journey and to discover the gender of their babies through genetic DNA testing. Unlike any other blood test taken through pregnancy, this is a fun-filled experience with coffee, donuts, and great conversation.


Multicenter blinded study conducted 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.
