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 mum’s 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.

At SneakPeek Labs, a test process called non-invasive prenatal testing (NIPT) is used to analyse cell-free fetal DNA. Starting with a small sample of blood from mum, plasma is separated from whole blood by centrifuge, and extracted cell-free fetal DNA (cffDNA) is analysed 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
