Our customers say...

"I received the results of the twin zygosity test regarding my daughters today. For 32 years, I have been operating under the assumption that they are fraternal twins. My daughter, Pamela, however has always felt deep in her heart that she and her sister are identical. This test was a birthday gift to them. I can hardly wait until this evening when I present them with your letter. I appreciate the fact that my request was handled with such professionalism. The e-mails informing me of the progress of the test were especially nice. Thank you again."
-Donna (Painesville, OH)

The Zygosity Testing Process

Our lab extracts DNA from the swabs for zygosity analysis.
  1. Place your order through the online order form, or by mail, fax, or phone. You will receive your customized DNA swab kit in 2-5 business days. You can check the real-time status of your order from our website at anytime.
  2. Once you receive the kit, simply follow the instructions for swabbing to gently remove cheek (buccal) cells. These cells contain adequate DNA for the zygosity test.
  3. Return the samples to our lab in the postage-paid bubblewrap mailer.
  4. To confirm that our lab has received your samples, you will be notified by either an e-mail message or postcard.
  5. Our lab extracts and analyzes DNA from the swabs.
  6. Within 10 business days of receiving the completed swab kits, your zygosity test results will be mailed to you. Clients have the option of also receiving a copy of their test results via email.
