Know Tomorrow - Your Baby's Gender by 6weeks

FETAL DNA

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.

Frequently Asked Questions

A: Baby gender testing through Peekaboo is absolutely safe for both mother and baby because it is non-invasive. All that is required for testing is a small blood sample from the mother.

A: Peekaboo offers the very earliest gender detection of any DNA-based test and can be performed as soon as 6 weeks into the pregnancy. Our superior equipment and testing methodology make this possible. Use the Eligibility Calculator on this page to see when you can test. The test is not validated for earlier than 6 weeks. Learn more about the science.

A: The Peekaboo test may be taken as early as 6 weeks of pregnancy or later. Accuracy at earlier times is unknown. There is an increased risk of an incorrect female result prior to 6 weeks’ gestation as the fetal DNA could be below the detection limit of the assay.

A: DDC scientists isolate cell-free fetal DNA from the mother’s blood, followed by amplification of both Y-chromosome and autosomal-specific regions using the latest quantitative real-time PCR (Polymerase Chain Reaction) technology. Analysts are looking for the presence of the Y chromosome, which only males have. If the Y chromosome is present, then the baby is a boy; if it is not present, then it’s a girl! Learn more about PCR.

A: This test has not been validated for multi-fetal pregnancies. If you are expecting twins or other multiples, we suggest relying instead on ultrasound and ultrasound 4D for determination of your babies’ sexes.

A: We understand Peekaboo is an important test for our customers, which is why we keep test times to a minimum. Before scheduling your gender-reveal party, please consider possible shipping delays or the need for additional sample testing. We suggest waiting to schedule your party until you have your test report in hand.
