Our state-of-the-art laboratory compares the DNA profiles across up to 28 genetic markers. Identical twins share 100% of their DNA, while fraternal twins share approximately 50%, similar to regular siblings. Results are delivered within 2-3 business days through our secure online portal.\u003c\/p\u003e\u003ch4\u003eWhen to Use This Test:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTwins (or their parents) want to know if they are identical or fraternal\u003c\/li\u003e\n\u003cli\u003eMedical purposes, identical twins may share health risks and conditions\u003c\/li\u003e\n\u003cli\u003eOrgan or tissue transplant compatibility assessment\u003c\/li\u003e\n\u003cli\u003ePersonal curiosity and family knowledge\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThis test provides 99.9%+ accuracy in determining twin zygosity.\u003c\/p\u003e\u003ch4\u003eFrequently Asked Questions\u003c\/h4\u003e\u003cdiv\u003e\n\u003cdiv\u003e\n\u003ch5\u003eWhat is a twin zygosity test?\u003c\/h5\u003e\n\u003cdiv\u003e\u003cp\u003eA twin zygosity test determines whether twins are identical (monozygotic, from one egg) or fraternal (dizygotic, from two eggs).
