Home Twin Zygosity DNA Testing $145

Our twin DNA testing package is complete with testing kit, DNA analysis and test results. Some companies advertise that you can make your own collection kit by using your own Q-tips®. However, we do not recommend this practice.  There is a risk of multiple DNA samples being found on Q-tips® that are not sterile, or that may be handled by more than one person.  For this reason, we rush you a DNA testing collection kit containing sterile buccal swabs to you at no charge. We also include a prepaid mailer to send samples back into lab.

It isn’t uncommon for test participants to live too far apart to get together and do a twin DNA test collection. For these cases, we offer the option to have multiple collection kits shipped. When you place your order, simply choose the option for an additional address. We send each collection kit for all addresses on your order within the contiguous USA with the same shipping method as the first. When multiple collection kits are ordered, the collection kits are linked through reference number and bar codes. Then, when the samples are received back in lab, they are matched to your case through the bar code and reference numbers.

The twin DNA testing collection process is very simple. DNA is collected on a cheek swab, also called a buccal swab. The swab is painlessly rubbed against the inside of the cheek. In this process, skin cells collect on the swab. We conduct all of our tests twice. For that reason, there will be 4 buccal swabs per person in your collection kit. Do two swabs on each side of the mouth. It is best to rinse the mouth with water and refrain from smoking or drinking coffee or tea for 2-3 hours before the DNA collection. Once the swabs have been taken, place the samples in the return prepaid pre-addressed mailer. Finally, simply drop the samples off at the courier’s location or box to send your kit back to the lab for testing.

When all samples are in the lab, you will be notified via email that testing has begun. We will email the results of your twin zygosity DNA test when the testing is complete, within 3-5 business days.  If hard copy results are ordered, the report is sent to the billing address unless otherwise noted.

We ship our collection kits Monday through Friday to physical addresses in the contiguous USA. Orders received and processed by 2:00 PM EST are shipped the same business day.  Orders received after 2:00 PM EST ship the following business day.
