Can I take a SneakPeek Test before I’m 8 weeks pregnant?

SneakPeek looks for Y chromosomes in the fetal DNA found in mom's blood. To avoid inaccurate test results, it's imperative to wait until you're 8 weeks pregnant to ensure the level of Y chromosomes is high enough to read.

I’m having twins. Can SneakPeek determine the gender of each one?

SneakPeek looks for male DNA in the fetal DNA found in mom's blood sample. 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, finding male DNA means at least one baby is a boy, but cannot distinguish if the second is a boy or girl.
