Twin Zygosity Test Order Form



What is included: A 24 marker Twin Zygosity DNA test, USPS Priority shipping of a Journey Genetic Testing DNA collection kit, detailed collection instructions, a prepaid return mailer for your DNA samples (USA addresses only), lab processing fees, and 100% accurate results from our AABB accredited testing laboratory.

Who is included: Two siblings to determine if they are identical twins (monozygostic) or fraternal twins (dizygosity).

When you will receive it: USPS Priority mail arrives within the USA in 2-3 business days.

If you need to send a kit to more than one address: You have the option of sending additional testing kits to other addresses if needed. Each additional kit is $14.95 and includes USPS Priority shipping, collection materials, instructions, and a prepaid return mailer for the samples (USA addresses only). If you wish to send more than one kit please indicate this on the order form.

When your results will be ready: 1 business days after the lab receives all of the DNA samples. Alternative non-standard DNA samples (anything other than a mouth swab) may require additional testing depending on the item submitted for testing. Non-standard DNA samples are not eligible for one business day processing.

If you don't want a kit mailed to your home or you are in a rush and don't want to wait for a kit to arrive: We offer the option to make your own DNA kit to allow you to be discreet if your circumstances call for that. Just select the "Make Your Own Kit" option on the order form and we will email you the instructions, your case number, and the address to send your samples to. The lab processing time is the same as with our Journey Genetic Testing DNA collection kit.
