Additional information

Identical twins originate from a single fertilized egg, called a zygote. The zygote, which usually develops into a single child, divides early in development to form two embryos, creating twins with the same DNA. In contrast, dizygotic twins develop when two different eggs in the mother's uterus are fertilized by two different sperm cells. Dizygotic twins will not have exactly the same DNA.

The twinship test we offer can determine whether two twins are identical twins or not. The test protocol is very rigorous and precise. It includes the reading of 22 DNA sequences (22 loci), giving the test an absolute percentage of certainty.

Process

After ordering your test, you will receive a collection kit that includes 2 swabs. You'll find the collection instructions in the envelope. This is a painless process.
Register your kit and personal information in your customer portal on the Adnà website.
Return your sample (in its original envelope) to the laboratory for sequencing and analysis.
You will receive an e-mail notification that your test report has arrived in your Adnà customer portal.
Results are normally ready in five business days after reception of your samples at the laboratory.
