We know it's hard to wait! SneakPeek looks for Y chromosomes in the fetal DNA found in mom's blood. To avoid inaccurate test results, it's imperative to wait until you're 8 weeks pregnant to ensure the level of Y chromosomes is high enough to read. Already purchased the test? No worries, you can hold on to it until you're 8 weeks pregnant – the test kit is good for a year. If you're not sure you're at 8 weeks yet, use our easy pregnancy calculator to double check.

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).

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 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.

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.

SneakPeek cannot confirm pregnancy. The test looks for male chromosomes in the fetal DNA found in mom's blood. If there is no fetal DNA in mom's blood, the test will return a girl result, because mom is a girl. On the off-chance that the test is contaminated with outside male DNA (even pets!), it may return a boy result. Please confirm pregnancy with your doctor prior to taking SneakPeek.

The SneakPeek Early Gender DNA Test is a non-invasive prenatal test (NIPT), and it's safe for both mom and baby.

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.

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.

SneakPeek looks only for the presence of Y chromosomes and is extremely sensitive and accurate. No blood thinners or other drugs are known to impact SneakPeek gender results.

SneakPeek is a DNA-based test, so hormone medications and fluctuations have no impact on results.

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.

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.
