Welcome to Trust Screen Lab, where we make twin zygosity DNA testing simple, informative, and stress-free. This specialized test helps determine whether twins are identical (monozygotic) or fraternal (dizygotic). Identical twins come from a single fertilized egg and share nearly the same DNA, while fraternal twins develop from two separate eggs and are genetically similar like typical siblings. When physical features or medical records don’t give a clear answer, our twin zygosity testing provides precise, science-backed results whether you’re seeking clarity for medical planning, genetic counseling, research, insurance needs, or personal knowledge.

​

The testing process at Trust Screen Lab is quick, non-invasive, and highly accurate. We collect DNA samples using simple cheek (buccal) swabs in a professional, controlled environment. When required, we follow strict identity verification and documented chain-of-custody procedures to protect the integrity of every sample. Each sample is carefully labeled, securely handled, and tracked from collection through analysis. We partner exclusively with accredited laboratories and apply rigorous quality standards, so you can feel confident in the accuracy and reliability of your results.
