How the Peekaboo Gender DNA Test Works


Beginning around just 5 weeks gestation, tiny fragments of DNA from a developing embryo travel through the placenta and into the mother’s bloodstream. If the embryo will be baby boy, this DNA will carry a Y chromosome. If the embryo will be a baby girl, the DNA will not have a Y chromosome.

Our scientists carefully analyze the mother’s blood sample with the most advanced quantitative PCR technology to look for this Y chromosome. The technology used is so sensitive, it’s able to determine if the baby is a boy or a girl as early as 6 weeks into pregnancy.


The Peekaboo DNA Gender Test was studied in a clinical trial with 215 pregnant women at clinical sites across the US. The study showed an accuracy rate of 99.5%.*

To maintain the highest level of accuracy possible during your test, it’s important to ensure that it does not become contaminated at your home with any male DNA from pets, children, or a male partner. You can depend on us to do the same—your sample will only be handled by an all-female staff at our lab to help ensure its viability.
