SneakPeek looks for the presence or absence of male Y chromosome DNA in the blood sample provided. If we do not find Y chromosome, that means the test result will be “girl”, and both twins are girls. If we do find Y chromosome, that means the test result will be “boy”. In this case, one baby is for sure a boy, but she’ll need an ultrasound to determine if the second one is a boy or girl. It is still very helpful for mums to do our test, since they can start planning/preparing for a baby boy.
SneakPeek’s inconclusive rate is 1%. We can offer either a free re-test or full refund to you.
No questions asked, we will provide a full refund to you.
