While every person has her own DNA in her bloodstream, a pregnant woman’s bloodstream also contains DNA from her unborn child. Blood Testing 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. Blood Testing is 99.9% accurate at 6 weeks into pregnancy.

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, giving you confidence in your results.

Clinical studies have shown that fetal DNA clears from mum’s bloodstream between a few hours to 2 days after birth.

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.

This is a DNA-based test, so hormones do not impact results.

Testing looks only for the presence of Y chromosomes and is extremely sensitive and accurate. No blood thinners or other drugs are known to impact gender results.

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

You will receive your result within 5-7 working days of your blood draw.* 

*Subject to delays

This 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.
