What is a Twin Test?
Twin Zygosity Testing also known as a Twin Test is a DNA test that determines whether twins are identical or fraternal. This test helps identify the genetic relationship between twins by analyzing their DNA profiles.

Legal Twin DNA Test
A Legal Zygosity Twin Test can be used in situations that may require a birth certificate name change, adoption, or estate cases when twins are separated at birth.
Legal DNA tests require a chain of custody to be established, and samples will be tested and analyzed by our partner, an AABB-accredited DNA laboratory. This lab accreditation ensures your results are recognized by all state agencies nationwide.

Frequently Asked Questions
What method is used to collect my samples?
The standard method for DNA sample collection is a cheek swab. Cheek swabs are placed inside the mouth and brushed against both the left and right cheeks. Blood specimen collection is a more painful and invasive option, but it has similar accuracy. Blood samples are typically drawn from a vein in the arm or finger prick..
Can identical twins perform a paternity test?
Yes, identical twins can undergo a paternity test, but the results may not be conclusive for the following reasons:
- Identical DNA: Identical twins develop from a single fertilized egg that splits into two embryos, resulting in them sharing nearly 100% of their DNA.
- Standard paternity tests: These tests typically compare DNA markers between the child and the potential father. In the case of identical twins, both twins would match equally well with the child’s DNA.
What distinguishes a sibling DNA test from a twin DNA test?
The main difference between a sibling DNA test and a Twin DNA test is as follows:
Sibling DNA Test: This testing option determines if 2 people share a common biological parent/s to prove siblingship. Results are often expressed as a probability of siblingship
DNA Twin Test: This testing option determines if twins are identical or fraternal. Results are usually more definitive, clearly indicating identical or fraternal
What if one twin cannot provide a sample?
When one twin is unavailable to participate in the DNA testing process, using this option will not be possible. The nature of a Twin Zygosity DNA Test requires samples of both twins be submitted to the laboratory to determine if the twins are either identical or fraternal.
