Fast, Powerful and Proven

The DNA Twin Zygosity Test will conclusively confirm whether a set of twins are Identical Twins or Fraternal Twins. It is not always 100% conclusive during birth whether a set of twins are identical or fraternal. The only way to conclusively confirm zygosity is through genetic testing. The DNA Twin Test can be taken by twins of all ages.

It is very rare for families to require the twin test for legal purposes, but we also offer a legal option for DNA Twin testing.

"Split Kit" option for families who do not live in the same city

If the individuals to be tested live in different cities, or even different countries, we can split the kit and send each component to a different address. Since the kits are individually barcoded, the samples will still be tested together even if the are sent back separately. To order a split kit, please write the following into the comments box of the online order form "Please split kit". Please also indicate the name and address to send each component. For example, please state "send one of the kits to... (specify one of the twin's name and address)" and "send the other kit to... (specify the other twin's name and address).
