What twin zygosity testing at the Omaha office determines
A twin zygosity DNA test determines whether twins are identical (monozygotic) or fraternal (dizygotic). Identical twins share essentially the same DNA at every marker location. Fraternal twins share about 50%, the same as any other pair of full siblings. At the Omaha office, both twins come in for professional collection during the same visit.
When zygosity testing is worth doing
-
Hospital or delivery records were unclear or missing at birth.
-
Adult twins want to confirm zygosity for medical planning (some genetic risks are shared between identical twins but not fraternal).
-
Personal curiosity or family history documentation.
-
Discussions with a medical provider about organ donor matching or shared genetic risks.
How accurate is a twin zygosity test?
When both twins provide viable cheek swabs, the result is scientifically conclusive. The comparison runs at 24 DNA genetic markers plus Amelogenin (for gender identification) with dual processing at a US-based AABB-accredited and CAP-certified lab.
When zygosity testing isn't the right test
If the two people being tested aren't confirmed twins (born from the same pregnancy), a standard sibling test is the right test. Zygosity testing assumes both participants were born from the same pregnancy and answers whether they came from one egg or two.
