What Is SneakPeek® Clinical?

  • DNA TEST
  • CONCIERGE STYLE
  • PERSONAL AND ATTENTIVE SERVICE

SneakPeek Clinical is an early gender DNA detection test offered to women starting at 8 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 imaging center 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.

DNA & Donuts is a breakfast party for expectant mothers where they can find out the gender of their babies starting at 8 weeks! Sacramento Imaging hosts a unique SneakPeek Clinical social event every Wednesday from 10-11am 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.

How does SneakPeek® work?

Multicenter blinded study conducted at four ultrasound clinics in 2015

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 the male Y chromosome in the blood sample provided starting at 8 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 Studies

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 8 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.

We Are Open For Business!

~ We will be limiting our schedule to no more than 8 patients per day. This allows time for us to see patients, have them go to the bathroom, clean the room & waiting area, etc.

Family members are welcome to attend appointments with patients.

~ In order to ensure the safety of staff and other patients, it is important for patients and visitors to be wearing masks.

~ Please arrive no earlier than 10 minutes before your scheduled appointment time.

~ If you arrive early and see another family/patient in the waiting area, please wait in the hallway until they exit. The waiting room is small and having many people in there at once would go against social distancing protocol/patient & staff safety.

~ Please use the hand sanitizer at the front desk when entering the waiting room.
