Non Legal Twin Zygosity Test
With our non-legal Twin Zygosity Test, you can collect DNA samples privately and confidentially in your own home. When all testing procedures are carefully followed, the results of the test will be as accurate as with any other collection procedure. However, the information obtained ca not be used in court proceedings because the process does not follow approved chain of custody requirements.

Legal Twin Zygosity Test
Legal Twin Zygosity Testing follows the strict requirements of chain of custody, and therefore can be admitted as evidence in court. If the purpose of testing is to conclusively determine genetic relationships for custody, child support or inheritance in a legal or government proceeding, our binding legal testing protocol is the appropriate choice.
