Frequently Asked Questions
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
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 SneakPeek test is sensitive
enough to find even a single Y chromosome, giving you confidence in your results.
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?
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 (or more!),
finding male DNA will confirm at least one baby is a boy, but cannot distinguish if 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
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.

SneakPeek Clinical is a non-invasive prenatal test (NIPT), and it’s safe for both mom and baby.
