"My family and I would like to take the time to thank you for quick and precise testing of our daughters DNA.  We were told at their birth in December that they were fraternal twins but in my heart I knew they were identical and wanted to pursue it further.  Had it not been for your buccal testing we may have gone through life telling them the wrong information so again we thank you and will highly recommend your services to anyone who is interested in zygosity testing! " -Sue (Bellingham, MA) more...
