What's Included in Your Twin Zygosity DNA Test Kit?

The $159 base order includes testing for two twins, with one collection kit shipped to one address. Your order includes the supplies and laboratory analysis needed for the number of participants selected at checkout.

• Cheek-swab collection supplies: Sterile swabs for collecting DNA from each participating sibling at home.
• Separate DNA sample envelopes: Keep each participant's swabs labeled and packaged separately for laboratory identification.
• Collection instructions and Result Notification Form: Guidance for preparing the samples and specifying the authorized results recipient.
• Laboratory testing: Twin zygosity analysis using 24 DNA genetic markers plus Amelogenin, with dual processing and all laboratory fees included for the selected participants.
• Prepaid U.S. FedEx shipping: Delivery of the kit and tracked return shipping for the completed samples and paperwork within the U.S.
• Private results and personal support: An emailed PDF report and access to a DNA Specialist for help with collection, case updates, and results.

Additional siblings cost $100 each when selected in your order. Any spare collection supplies in the kit do not include laboratory testing for participants who have not been added to the order. Separate-address kit delivery and legal chain-of-custody collection require the appropriate testing option.

How It Works

Step 1 · Order and receive the kit

Select the number of siblings from the same pregnancy who will be tested, from two through eight. One kit ships to your chosen address within 1 business day in plain FedEx packaging.

Step 2 · Collect cheek swabs

Collect two cheek swabs from each participating sibling, rubbing each swab against the inside of the cheek for 60 seconds as directed in the kit instructions. A parent or guardian can collect samples from newborns and young children. Keep each person's swabs separate throughout collection.

Step 3 · Air-dry the swabs

Let swabs air-dry at room temperature for at least 30 minutes before packaging.

Step 4 · Package samples separately

Place each participant's dry swabs in their own labeled DNA sample envelope. Complete the Result Notification Form for everyone being tested, making sure the participant identifiers match the sample envelopes.

Step 5 · Ship samples to the lab

Place the labeled sample envelopes and completed Result Notification Form in the included prepaid FedEx return envelope for U.S. shipments. Return the package through FedEx using the provided label.

Step 6 · Lab logs samples and confirms intake

Your specialist confirms intake.

Step 7 · Zygosity comparison

The lab runs the zygosity comparison at 24 markers plus Amelogenin with dual processing.

Step 8 · Report delivery

Your full-color PDF report is emailed to the authorized recipient within 1-3 business days after all required samples and the completed Result Notification Form have been received, accepted by the laboratory, and placed into processing. Shipping time, weekends, and holidays are separate from the laboratory turnaround.
