Frequently asked questions.

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).

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 is a DNA test that looks for male chromosomes in the cell-free fetal DNA (cffDNA) found in mom’s blood, a process that was first established in 1997 and refined in a multitude of scientific publications since. Urine-based tests have no scientific validity, as there are no gender markers in urine. See this blog post for more details.

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. This pregnancy calculator makes it easy!

Yes! See our pregnancy 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 pregnancy calculator makes it easy to see if you’re eligible.

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 is good for a year.

Not sure if you’re at 8 weeks yet? Use our easy pregnancy calculator to double check.

Yes, you can purchase the SneakPeek Test and hold on to it until you are 8 weeks into pregnancy. Stored at room temperature and unopened, the test kit is good for one year after purchase.

SneakPeek looks for male DNA in the fetal DNA found in mom’s blood sample. In the case of identical twins, if male DNA is found, then both babies are boys. If no male DNA is found, then both babies are girls. For fraternal twins, finding male DNA means at least one baby is a boy, but cannot distinguish if the second is a boy or girl.

Yes, you can! SneakPeek looks for male DNA in the fetal DNA found in mom’s blood. In the case of identical triplets (or more!), the presence of male DNA means all three babies are boys. The absence of male DNA means all three babies are girls. For fraternal triplets, finding male DNA means at least one baby is a boy, but the test cannot confirm if the others are boys or girls.

Clinical studies have shown that fetal DNA is undetectable in mom’s bloodstream between 1 to 2 days after birth. Therefore, a previous male-bearing pregnancy will not affect your current test results.

Clinical studies have shown that fetal DNA clears rapidly from the maternal bloodstream, within 1-2 days. Therefore, a miscarriage will not affect your current test results.

SneakPeek is a DNA-based test that looks for male chromosomes in the fetal DNA found in mom’s blood. Therefore, hormonal changes such as those caused by breastfeeding do not impact SneakPeek test results.

SneakPeek is a DNA-based test, so hormones do not impact results.

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.
