Testimonials
I was very satisfied with the service I received from ADNÀ and I highly recommend this company.
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.

Questions?
What is the difference between a twin test and a sibling test?
A twin test determines whether twins are monozygotic (identical) or dizygotic (fraternal) by comparing their DNA.
A sibling test, on the other hand, evaluates the biological relationship between two individuals to determine if they are brothers or sisters by analyzing the proportion of shared DNA.
How long will it take to receive my results?
The time required to process and analyze your sample depends on the type of report you have ordered. Once it arrives at the laboratory, processing times are as follows:
- Paternity and other filiation test kits are processed and sent out to you within 24 hours. Once you have sent back your sample and it has reached the laboratory, results are normally ready within 2 days following reception at the laboratory.
- Biomarker tests are processed in 7 to 14 working days.
- Ancestry, sports performance, nutrition, skincare, talent & personality, microbiome, genetic predisposition and pharmacogenetics test kits are processed and shipped to you within 24 hours and results are normally received within 30 to 60 days of placing your order.

What types of genetic tests do you offer?
Our tests fall into several categories:
- Filiation tests, which identify whether there is a familial relationship between two or more individuals.
- Well-being tests, which provide information on how your genes can influence your lifestyle, preferences, health, and well-being.
- Health tests, which help identify genetic predispositions to certain diseases or how the body metabolizes specific medications.
- Ancestry tests, which offer insights into an individual’s family origins and genetic lineage across different historical periods.
- Microbiome tests, which identify and quantify the various bacteria and microorganisms present in a person’s microbiome.
- Biomarker tests, which measure specific substances in the blood to assess an individual’s health, detect diseases, or monitor their progression.
What are the limits of your tests?
- Our tests are for informational and educational purposes. They are not intended to be used as a diagnostic tool. Your traits are not only influenced by genetics, but also by many other factors such as social and geographical environment, education, lifestyle, etc. We encourage you to interpret the results with caution, and to consult healthcare professionals for further evaluation if necessary.
The information extracted from the tests and presented in our reports should be considered as indications of predisposition and not as definitive diagnoses. Their relevance may vary according to numerous environmental factors.
What is the scientific basis for your tests?
- A parentage test uses DNA to establish family relationships. It analyzes genetic markers to identify biological relationships between parents and children, grandparents, uncles, aunts, twins and siblings. DNA comparison reveals specific genetic similarities, indicating a family relationship. These tests exploit genetic patterns of inheritance shared by members of the same family. In this way, they can map out extended family connections, offering a precise overview of biological links. Our parentage tests offer close to 99.9% accuracy.
- Our lifestyle and health tests are based on a combination of cutting-edge technologies and internationally recognized scientific studies. DNA sequencing is performed using Illumina technology. This technology can analyze over 700,000 genetic markers. Added to this is the integration of peer-reviewed studies accepted by the international scientific community, which enable a connection to be made between a particular gene and a potential predisposition. This ensures that reports are based on recent, relevant scientific data that reflect an established scientific consensus.
What information can I find in your genetic reports?
- Depending on the type of test you choose, you can expect to receive detailed information about your parentage, your ancestry, personalized health advice, or insight into specific genetic traits.
Can your tests identify predispositions to certain diseases?
- Yes, our Genetic Predisposition Test answers this question. However, this test is not intended for diagnostic purposes.
