An At-Home Early Gender Test That is Actually Accurate — Using Your Baby’s DNA

Published on May 6th, 2019 and Updated on April 8th, 2021

Technology is ever-evolving within the pregnancy realm. Gateway Genomics, the parent company of the SneakPeek At-home and SneakPeek Clinical, is the leader in providing accurate gender results using fetal DNA. If you’re pregnant, you now have access to an easy test that gives you the ability to know your baby’s gender as early as 8 weeks into your pregnancy with our baby gender predictor. Rooted in DNA science, our early gender determination test continues to make its way into the lives of expecting mothers — just like you — around the world.

How Does the SneakPeek Early Gender DNA Test Work?

SneakPeek analyzes cell-free fetal DNA (cffDNA) that is released by the placenta and circulates in mama’s blood. While every person has their own DNA within their bloodstream, a pregnant woman also has the cffDNA of her unborn child. From a sample of mom’s blood, SneakPeek Labs extracts cffDNA and runs a test to detect the Y chromosome. Females only have X chromosomes, so if Y chromosomes are found, the baby is a boy. If they are absent, the baby is a girl. The SneakPeek test can analyze cffDNA using the collection of capillary blood (i.e. the blood that is available from a prick to your finger) or intravenous blood (i.e. blood that comes directly from your vein.) In our peer-reviewed study recently published in the Journal of Pregnancy and Child Health, gender was determined with 99.9% accuracy.

How Do You Take the Test?

Now that you’ve learned why our prenatal technology works, are you ready to take your own test? First, we start by sending our at-home kit, designed to make the process as simple as possible. When actually taking the test, what should you expect? The test is easy to use, can be performed at-home (or we have a clinical option) and it only takes a total of 20 minutes to complete with an average of 5 minutes, hands-on time. It is quick, simple, and easy. Just make sure to follow the directions carefully, so that we can provide you with an accurate, fast result.


  • Before taking the test, you must clean your surrounding area (i.e. the surface you will be using the test on) thoroughly. Then, make sure you also wash your hands: front, back, and under your fingernails. This helps to ensure an accurate result.


  • Do not be in the presence of males when taking the test. Why? If you come in contact with any male DNA (i.e. Y chromosomes) — even from your male dog — you can get an inaccurate result. Remember, we are searching for the presence of a Y chromosome, to determine if your baby is a boy or girl.


  • Next, using a lancet included in the SneakPeek kit, you’ll stick your finger to provide a small sample of your blood for analysis at our state-of-the-art lab. Don’t worry, we only require 7-10 drops of blood (500 microliters) to be placed inside your kit vial.


  • Once you’ve taken the test, mail your kit back to SneakPeek Labs in our prepaid envelope, and your results will be sent to your email inbox within a day of us receiving your kit.

How Accurate is The SneakPeek Test?

Unlike urine-based early gender determination tests, SneakPeek is the only one that uses non-invasive prenatal testing (NIPT), a DNA-based analysis. With 99.9% accuracy, mamas-to-be continue to gravitate toward our test again and again.

Since inception, we’ve delivered over 350,000 fast, affordable prenatal genetic tests with highly accurate gender results in the first trimester of pregnancy to mamas such as yourself. What are you waiting for? You can get your very own SneakPeek Early Gender DNA Test or utilize the Clinical version at our ultrasound and Obgyn partners nationwide. Find active locations, here.
