Key Reasons for Twin DNA Testing:

  • Medical Necessity: Identical twins share the same DNA, making them optimal matches for organ or tissue transplants. Knowing zygosity helps identify shared genetic risks for conditions.

  • Confirming Zygosity: Physical observations (e.g., placenta analysis) at birth are not always accurate. A DNA test can definitively confirm whether twins are identical or fraternal.

  • Health and Medical History: If one identical twin has a genetic illness, the other is likely at risk. Knowing they are identical alerts doctors to monitor both, whereas fraternal twins are no more likely to share conditions than siblings.

  • Curiosity and Records: Parents often take the test to satisfy curiosity, especially if birth records are lost or ambiguous.

  • Rare Paternity Cases: In rare instances, fraternal twins can have different fathers, requiring DNA testing for both.
