	Our customers say... "My family and I would like to take the time to thank you for quick and precise testing of our daughters DNA. We were told at their birth in December that they were fraternal twins but in my heart I knew they were identical and wanted to pursue it further. Had it not been for your buccal testing we may have gone through life telling them the wrong information so again we thank you and will highly recommend your services to anyone who is interested in zygosity testing!

Are your twins or triplets identical or fraternal?

Offering A Twin DNA Test That Is Affordable & Accurate

Sometimes it is unclear whether same-sex twins are identical twins or fraternal twins. A bloodless twin DNA test, or zygosity test, offers a conclusive answer. In particular, same-sex twins who were dichorionic (2 placentas) are actually genetically identical about 30% of the time. Also, for deliveries where the placental anatomy was not confirmed, are ideal candidates for a twin DNA test. Using an at-home collection kit, DNA is easily obtained from cheek swabs and returned to our lab through the mail for analysis. The twin DNA test examines special DNA sequences that are used in human identity. There are several ordering options or call and speak with us at 1-866-894-6362.
