Frequently asked questions
Learn more about SneakPeek Clinical Early Gender DNA Test
How does SneakPeek work?
While every person has her own DNA in her bloodstream, a pregnant woman's bloodstream also contains DNA from her unborn child. SneakPeek looks for male chromosomes in a small sample of your blood. If male chromosomes are found, that means baby is a boy. If none are found, baby is a girl. SneakPeek is 99.9% accurate at 6 weeks into pregnancy.
What is the SneakPeek process?
At SneakPeek Labs, a test process called non-invasive prenatal testing (NIPT) is used to analyze cell-free fetal DNA. Starting with a small sample of your blood, plasma is separated from whole blood by centrifuge, and extracted cell-free fetal DNA (cffDNA) is analyzed for Y chromosomes, which are found only in males. The test is sensitive enough to find even a single Y chromosome.
I've previously had a boy. Will that skew my results?
Clinical studies have shown that fetal DNA clears from mom's bloodstream between a few hours to 2 days after birth.
I'm having twins. Can SneakPeek determine fetal sex for each one?
For identical twins, if male DNA is found, both babies are boys; if none is found, both are girls. For fraternal twins (or more), finding male DNA confirms at least one baby is a boy, but cannot distinguish whether the second is a boy or girl.
Do hormone disorders such as PCOS affect my results?
SneakPeek is a DNA-based test, so hormones do not impact results.
Do blood thinners affect my 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.
Is this test safe?
SneakPeek Clinical is a non-invasive prenatal test (NIPT), and it's safe for both mom and baby.
How quickly can I get my results?
Your blood sample is shipped to SneakPeek Labs via FedEx Priority Overnight shipping. Expect your result email between 4-8pm Pacific Time the day your sample is received by SneakPeek.
Are results guaranteed?
SneakPeek Clinical is the most accurate early gender test on the market. If your test result does not match the gender of your newborn, you'll receive a full refund.
How is my privacy protected?
SneakPeek tests only for baby's gender, no data is gathered about disease states or other health information. After testing, your DNA sample is disposed of by a professional chemical management company in compliance with federal standards. SneakPeek never shares your results with anyone other than the email address you provide.
