Understanding Twin Zygosity DNA Testing

Twin zygosity DNA testing reveals if twins are identical (monozygotic) or fraternal (dizygotic). You can’t always tell by looks or placenta count, and only a DNA test gives you scientific certainty. Identical twins share the same genetic profile, while fraternal twins share roughly half, similar to other siblings. 

Here’s how families benefit from this service:

• Clarifying medical plans that depend on zygosity status
• Evaluating eligibility for blood or tissue donor matches between twins
• Qualifying for research or genetic studies
• Resolving family questions about biological relationships

Medical professionals across Houston frequently recommend DNA-based tests when appearance or hospital records do not provide clear answers. With Houston's rich medical and scientific resources, many parents seek this certainty before making healthcare choices. Our service simplifies the process by providing results and clear explanations, making next steps straightforward after you receive documentation.
