The Home Twin Zygosity DNA Test provides a reliable way to determine whether twins are identical or fraternal. This test compares the DNA profiles of both individuals to evaluate their genetic similarity. Identical (monozygotic) twins share nearly identical DNA, while fraternal (dizygotic) twins are genetically similar to typical siblings.
Understanding twin zygosity can be important for medical awareness, genetic planning, and personal knowledge. All samples are analyzed by an AABB-accredited U.S. laboratory using advanced technology and validated procedures to ensure accurate and dependable results.
DNA collection is completed privately at home using painless cheek swabs included in the kit. Collection kits are shipped quickly and discreetly, with prepaid return packaging included. If the twins are located in different cities or states within the contiguous United States, additional shipping addresses can be added during the ordering process so each participant receives their own collection kit.
Once all samples are received by the laboratory, results are typically available within a few business days. Home twin zygosity testing is intended for personal knowledge only. If you require testing for legal or official purposes, please contact our office to discuss available options.

“In my opinion I am very satisfied. I have an adult daughter that’s 24 years old now that I did not know I had.

I will definitely recommend this to anybody that needs to do a DNA test.”
