During pregnancy, cell-free fetal DNA is released by the placenta and can be found in mom’s bloodstream. Using a small sample of mom’s blood, SneakPeek tests for the presence of male DNA (Y-chromosomes). Y-chromosomes would only be present if mom is pregnant with a boy. If no Y-chromosomes are found, mom is carrying a girl. This method is known as noninvasive prenatal testing (NIPT) and is safe for both mom and baby. See the peer-reviewed published study that indicates this test is 99.1% accurate as early as 8 weeks into pregnancy in the International Journal of Pregnancy and Childbirth (Int J Pregn & Chi Birth. 2019; 5(4):135-137).
SneakPeek At-Home lets you use a simple finger stick to collect a small sample of blood in the comfort of your home. Choose SneakPeek Clinical if you'd like blood to be drawn for you in a clinical setting.
To take SneakPeek, you must be at least 8 weeks into pregnancy, which can be calculated using either the first day of your last menstrual period, or baby's estimated due date. Use our Test-ready calculator to see if you're eligible!
The first day you are test ready is 8 weeks after the first day of your Last Menstrual Period (LMP) or 32 weeks before your Estimated Due Date (EDD). Use our eligibility calculator!
We know it's hard to wait! To avoid test results that are inconclusive or inaccurate, we don't recommend taking the SneakPeek test until you're at least 8 weeks into pregnancy. But don't worry, if you've already purchased the test, you can hold on to it until you're 8 weeks pregnant – the test kit components are good for a year.
In laboratory testing, SneakPeek accurately determined fetal sex in 99.1% of 108 pregnant women at 8 weeks gestational age. See the peer-reviewed study in the International Journal of Pregnancy and Childbirth (Int J Pregn & Chi Birth. 2019; 5(4):135-137). In a separate laboratory test, fetal sex was accurately determined in 99.6% of 241 pregnant women at 9 weeks gestational age and later into pregnancy. See the peer-reviewed study in the Journal of Pregnancy and Child Health. (J Preg Child Health. 2017; 4:358).
Yes you can. If we detect the presence of male DNA then we can confirm that 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. We are not able to provide gender information specific to multiple babies at this time.

your sample before the USPS postal cutoff time of 12 pm); and results delivered 8 hours after your sample is checked in.

The accuracy of SneakPeek earlier than 8 weeks into pregnancy has not been evaluated.
Yes you can. Since we can’t control for any contamination during the collection of your sample, it is very important to follow the instructions you get with your test kit exactly. Contamination of your sample with male DNA will yield a false positive result.
Carefully follow all instructions and make sure no males are present or recently present where you choose to take the test. Sanitize the surface you are collecting your sample on. Make sure to thoroughly sterilize your hands and focus on scrubbing your fingertips and under your nails. Rinse hands thoroughly and allow them to air dry. Do not use a towel or touch anything. Do not allow anyone who has male DNA (including your partner!) to open your test box or touch any of the contents inside before, during, or after sample collection. Do not allow a male to help you in any way to collect your sample.
A miscarriage that has occurred more than 3 months prior to taking the test has no effect on the accuracy of the test.
A previous pregnancy carrying a male has no effect on the accuracy of our test.
We completely stand behind our product and will gladly give you a full refund if our result does not match the gender of your newborn baby.
