Who can take SneakPeek?

SneakPeek is proven to be 99.1% accurate at 8 weeks into pregnancy. If you’re not 8 weeks pregnant yet, no worries! The gender test kit is good for a year, just hold on to it and take the gender test at home when you’re at 8 weeks into pregnancy or more.

If you’re currently breastfeeding, that won’t affect the SneakPeek test results. SneakPeek looks for male chromosomes in the fetal DNA found in mom’s blood. Because breastfeeding is a hormonal change that has no impact on genetics, it has no impact on the gender blood test accuracy or results.

If you had a boy in a previous pregnancy, that won’t affect your gender reveal test results, either. Fetal DNA disappears from mom’s bloodstream within 3 days of giving birth, so have no fear, the analysis for your current pregnancy will be correct!

Results You Can Trust

How does your blood sample become a boy or girl test result? During pregnancy, fetal DNA is released by the placenta into mom’s bloodstream. SneakPeek tests for male chromosomes in the fetal DNA found in mom’s blood. Moms normally have only female chromosomes, so if male chromosomes are detected in the DNA of the fetus, baby is a boy. If no male chromosomes are detected in the DNA of the fetus, baby is a girl.

• 99.1% accurate at 8 weeks into pregnancy

Still wondering?

SneakPeek is clinically proven to be 99.1% accurate.

SneakPeek tests for male chromosomes in the fetal DNA found in mom’s blood, so it's very important to keep your sample clean of outside male DNA. In-depth instructions are provided in our test kit, but in summary: 1) Clean and sanitize a flat surface on which to place the test kit, 2) Thoroughly wash both hands and under all fingernails, and let them air dry, 3) Ensure no males (even male animals!) touch the test kit components. These steps help ensure any male DNA found by SneakPeek is from fetal DNA.

Yes you can! The test kit is good for a year, with an expiration date at the bottom of every box. Just leave the plastic wrap on, and only open the kit when you're ready to take the test.

Yes! See our test eligibility calculator. You can take the SneakPeek Test when you are 8 weeks into pregnancy, which is 8 weeks after the first day of your Last Menstrual Period (LMP), or 32 weeks before your Estimated Due Date (EDD). The test eligibility calculator makes it easy to see if you're eligible.
