A recent study concludes that SneakPeek's gender prediction test has been found to be over 99% accurate when determining fetal sex, as confirmed at time of birth!

The SneakPeek test is accurate any time from 6 weeks into pregnancy to birth. SneakPeek looks for Y chromosomes in the fetal DNA found in mom's blood. The amount of fetal DNA increases the further mom is in her pregnancy, so the test can be taken with accurate results starting at 6 weeks until birth. Not sure if you're at 6 weeks yet? Use our easy test eligibility calculator to double check.

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 recently published study that indicates this test is over 99% accurate as early as 6 weeks into pregnancy.

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.

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

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.

Yes, your results are still reliable! Even if a doctor’s dating scan places you as early as 6 weeks into pregnancy when you took the SneakPeek test, you can still trust your results. A recent study concluded that, when compared at time of birth, SneakPeek was over 99% accurate in determining fetal sex for babies who were 6 weeks into gestational age. In this study, LMP was one of the measures used to establish 6 weeks, so if you were at least 6 weeks into pregnancy using LMP, you can rely on your 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.

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.
