Find Out if Twins Are Identical or Fraternal - Even from Different Locations

My Forever DNA’s Twin Zygosity DNA Test Kit accurately determines whether twins are monozygotic, also known as identical twins, or dizygotic, also known as fraternal twins, using a simple, painless cheek swab collection process.

Our unique Multiple Location Kit makes it easy to test twins who live in separate homes, cities, or states. Whether you are testing newborns, children, teens, or adults, My Forever DNA® delivers fast, accurate, and confidential results you can trust.

As the original creators of the Multiple Location Home DNA Test, we have refined every detail to provide peace of mind with unmatched precision, simple sample collection, and personalized care.

Why Choose My Forever DNA® for Twin Testing?

100% Confidential & Discreet: Your privacy is our priority. Kits arrive in plain FedEx packaging, and your personal information is handled with care and confidentiality throughout the testing process.

Fast Results You Can Trust: Receive your confidential results within 1-3 business days after samples arrive at the laboratory and are accepted for testing. Results are delivered securely by email, mail, or both, depending on your selected preference.

Transparent Pricing, No Hidden Fees: All lab fees and shipping costs are included in your purchase. No hidden charges. No surprise processing fees.

Reasons Families Choose Twin Zygosity Testing

  • Personal Curiosity and Insight:
    Understand more about your twins’ shared traits, genetic connection, and biological relationship beyond physical appearance.
  • Medical and Health Planning:
    If one identical twin faces a health condition, the other twin may share similar genetic risks. Zygosity confirmation may help families better understand potential health planning and preventive care discussions with a medical provider.
  • Lost or Unclear Birth Records:
    When delivery records, hospital records, or placental reports are missing, unclear, or contradictory, DNA testing can provide definitive answers about twin type.
  • Clinical and Legal Applications:
    Identical twin confirmation may support donor matching for stem cell or organ transplant discussions, medical research, or legal situations where genetic identity may need to be documented. If you need court-admissible results, please review our Legal DNA Testing options .

Experience the My Forever DNA® Difference

We understand that zygosity testing is more than just science - it is a meaningful moment for families. That is why we provide a seamless, stress-free, and supportive experience from the moment you place your order to the day your results arrive.

Need a Different Twin DNA Testing Option?

If the multiple-location twin zygosity test is not the best fit, My Forever DNA® offers additional testing options.

Are both twins able to collect samples from the same location?
If both participants can complete collection from the same home or location, our Standard At-Home Twin Zygosity DNA Test Kit may be the better option.

Need to use a discreet or alternative DNA sample?
If you need testing using a discreet or alternative DNA sample instead of standard cheek swabs, please view our Discreet DNA Testing Kit .

Confirm if your twins are identical or fraternal - no matter the distance - with accurate, fast, and private results from My Forever DNA®.

1-3 Business Day Results After Both Participants’ Samples Are Received

Your results are completed and emailed within 1-3 business days after both participants’ DNA samples have been received, accepted by the laboratory, and placed into processing. In some cases, results may be completed even sooner.

Because this order includes separate DNA kit shipments, sample tracking works a little differently. You will not receive a sample-received confirmation until both participants’ completed DNA samples have been returned to the laboratory and placed into processing.

Please use the return FedEx tracking numbers included in your email to monitor when each participant’s DNA samples have been delivered back to the laboratory.

What to Expect Once Both Samples Are Received

  • Personal Confirmation From Your Dedicated DNA Specialist: Once both participants’ samples have been received and placed into processing, your dedicated DNA Specialist will personally confirm your case status.
  • Clear Result Turnaround Timeline: You will receive a clear timeline so you know when to expect your confidential DNA test results.
  • Direct Access to a Real Person: If you have questions or need clarification, you can speak with a real My Forever DNA® Specialist instead of relying on an automated portal.
  • Secure Results Delivered by Email: Your completed results are sent as a secure, full-color PDF directly to the authorized recipient by email.
  • No Portal, No Barcode Activation, No Impersonal Process: There is no online portal to navigate, no barcode activation required, and no confusing automated system.

Important Turnaround Information

Results are processed and emailed Monday through Friday only. Weekends and holidays are not included in the 1-3 business day result turnaround time.

The Human Advantage Behind Every Accurate DNA Result

We understand how personal, emotional, and important DNA testing can be. That is why My Forever DNA® does things differently by creating a more private, guided, and human DNA testing experience from start to finish.

You should not have to receive life-changing DNA test results through an impersonal portal with no clear way to speak to a real person.

Once your DNA samples arrive at the laboratory, your case is assigned to a Dedicated DNA Specialist who helps guide the process and keep you informed.

  • Personal confirmation when your DNA samples are received and placed into processing
