Early Gender DNA Testing Q&A



How does SneakPeek® work?

SneakPeek® utilizes the natural process of shared fetal DNA circulating inside the mother’s bloodstream. From the small sample of blood your 4D Sprouts partnered licensed phlebotomist obtains, we are able to test for the presence of male DNA. If it is detected then the baby’s gender is male and if it is not detected then the baby’s gender is female.


What is the price of the test & how is it paid?

$129 paid at 4D Sprouts via cash or major credit/debit card.  Insurance is not accepted.


What is the di­fference between SneakPeek® and SneakPeek® FastTrack?

SneakPeek® is our fi­rst entry option into high-speed DNA test results to identify the gender of your baby with a total turnaround time of  3-5 days, whereas FastTrack ($20 upgrade fee) features results within 2 days.

*Turnaround times vary depending on location and are based on postal delivery days (Monday-Saturday). The 3 to 5 days is an average time based on shipping times back to our laboratory facility; results delivered 24 hours after your sample is checked in.


How early in my pregnancy can I test for my baby’s gender?

You are test ready at 9 weeks of pregnancy.


Can I use SneakPeek® if I am having a multiple birth pregnancy?

Yes, you can. If we detect the presence of male DNA then we can confi­rm at least one of the babies is male. If we do not detect male DNA then we can confi­rm you are only having female babies.


How do I calculate when I can take the test?

You are test ready at 9 weeks after the fi­rst day of your Last Menstrual Period (LMP) or 31 weeks before your Estimated Due Date (EDD).


Can I use SneakPeek® if I am not 9 weeks into pregnancy?

No, do not take the SneakPeek® test until you are at least 9 weeks into pregnancy. We will not process any sample that does not meet our minimum threshold of gestational age. Our test ready threshold is 9 weeks after the first day of your Last Menstrual Period (LMP) or 31 weeks before your Estimated Due Date (EDD).


Do you test my blood for gestational age?

No, we do not test blood for gestational age. The information you provide on your signed Consent Form acknowledges that you have provided an accurate Last Menstrual Period (LMP) or Estimated Due Date (EDD) that will be used to measure how many weeks into pregnancy you are.


What is the accuracy of SneakPeek® Clinical Test at 4D Sprouts versus the at-home tests?

SneakPeek® Clinical tests are 100% accurate, compared to 99% accuracy on at-home tests.  In a blinded multi-center study performed in 2015 with samples collected at four clinics, SneakPeek® showed an accuracy rate of 100% for fetal sex identification. The results of this study may be reviewed here.

In controlled laboratory tests, SneakPeek® detected shared male fetal DNA in >99% of blood samples from pregnant women carrying male fetuses at 9 weeks gestational age and later into pregnancy. Male fetal DNA was not detected in blood samples from pregnant women carrying female fetuses.

In at-home testing, a validation study presented at the American Society of Human Genetics (ASHG) Conference showed that SneakPeek® Early Gender Test is highly accurate at determining baby gender as early as 9 weeks into pregnancy. The data from the validation study showed 98% accuracy, the results may be reviewed here.


How is the sample taken?

A licensed phlebotomist at 4D Sprouts will obtain the small blood draw.


Will my sample degrade during shipping?

No, once samples are sealed in the collection tube they are preserved for shipment.


What if the test is wrong?

Our lab, Gateway Genomics, offers a 100% refund to customers whose test results do not match the gender of their newborn baby. Our refund policy is available here.


Will the test tell me if something is wrong with me, my pregnancy or my baby?

No, SneakPeek® is not intended to diagnose any disease or medical condition. SneakPeek® was developed and its performance characteristics were determined by Gateway Genomics, LLC. SneakPeek® has not been cleared or approved by the FDA.  As always, consult with your physician if you have concerns about the health of your pregnancy or the health of your baby or yourself.
