What Is A DNA Gender Reveal Test?

DNA Gender Reveal Tests are 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 the lab 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 lab.

How do DNA Gender Reveal Tests Work?

Multicenter blinded study conducted at four ultrasound clinics in 2015

DNA Gender Reveal Tests utilize 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.

DNA Gender Reveal Tests Accuracy Studies

Multicenter blinded study conducted at four ultrasound clinics in 2015

The purpose of this study was to assess the clinical performance of DNA Gender Reveal Tests (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 DNA Gender Reveal Tests.

Cell-free DNA was detected in all maternal blood samples. Y-chromosome DNA was detected in all samples from women carrying a male fetus. DNA Gender Reveal Tests 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. DNA Gender Reveal Tests accuracy, sensitivity, and specificity were each 100% for fetal sex identification. This blinded study showed that DNA Gender Reveal Tests are highly accurate for fetal sex determination in early pregnancy.

We Are Open!

~ 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.

~ Due to the Sacramento County Social Distancing Protocol patients are only allowed 5 ADULT VISITORS (Guests) at this time. Children are counted as a guest as well. Children are welcomed if they are supervised by another adult.

~ 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.

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

CANCELLATION POLICY. If you will not be able to appear for your scheduled appointment, you must notify Sacramento Imaging 24 hours prior to your appointment time. If you miss or cancel your appointment without giving the appropriate 24-hour notice, Sacramento Imaging may charge you a $25.00 cancellation fee.
