The Genovate DNA Twin Test is an at-home zygosity kit that conclusively determines whether a set of twins or triplets are identical (monozygotic) or fraternal (dizygotic). DNA is collected using a painless mouth swab in the privacy of your home. Samples are returned to the laboratory using the included prepaid envelope, and results are delivered by email within 1 to 3 business days of sample receipt. Private and confidential.
The Genovate DNA Twin Test is well suited for parents of twins or triplets who want a conclusive, lab-confirmed answer to whether their children are identical or fraternal, using a simple at-home mouth swab collection. Families in which participants live in different locations will find the split-kit option a convenient solution for collecting samples from each participant at separate addresses. Individuals and families who want private, discreet results without an in-person clinic visit will find the at-home format and secure online results platform a straightforward option. Healthcare providers, researchers, or educators working with multiples who need zygosity documentation will find the accredited laboratory report a reliable reference.
What is the difference between identical and fraternal twins?
Identical (monozygotic) twins develop from a single fertilized egg that splits into two embryos and share nearly 100% of their DNA. Fraternal (dizygotic) twins develop from two separate fertilized eggs and share approximately 50% of their DNA, similar to non-twin siblings. The DNA Twin Test analyzes genetic markers from each participant to determine which type of twinning occurred.
What if the participants live in different cities?
The kit can be split so that collection components are sent to each address separately. Each component is individually barcoded and tested together once all samples arrive at the laboratory. To request a split kit, write "Please split kit" in the Order Notes field at checkout and include the name and address for each participant.
Is there an age limit for testing?
No. The DNA Twin Test can be performed on individuals of any age, including newborns. If the participant is a minor, the legal guardian must sign the consent form.
How long are the test kits good for?
Test kits can be stored indefinitely before sample collection. After collection, samples should be returned to the laboratory within 3 months. Kits are stored at room temperature before and after collection.
