Our accreditations

An accreditation is a certificate that is issued by a third party entity. This is to ensure there is no bias and that the accredited certification bodies operate independently and objectively when deciding which genetic testing laboratories are to be awarded their certificate. Once a lab has this certificate, they may use it to their advantage as a proof of competency. Clients using an accredited DNA testing facility can really have their mind at rest that every operation being carried out within the testing facility follows very high standards.

Remember that accreditations are very specific; for example, ISO (The International Standards Organization) issues several possible accreditations but each is targeted to show credibility in a very specific area. Environmental management systems may have the ISO 14000 whilst ISO 9001 is specifically issued for excellence in quality management. When it comes to DNA testing laboratories, ISO may issue the ISO 17025 certification to those facilities that display outstanding Excellency in what they do.

With EasyDNA, laboratories analyzing your samples are ISO 17025 accredited. Click here to read more about the laboratory.


Paternity and parental DNA tests are very accurate. The results for DNA paternity testing are close to 100% accurate if the man tested is the biological father of the child or the children tested. In fact, in such cases, the probability of paternity is 99.99%. No DNA test can offer a 100% accurate result as paternity testing is partly based on a statistical calculation. The probability expresses the chances that the man tested is the biological father of the child and no other male within a population.

If the man tested is not the biological father, he is “excluded” from the paternal relationship with a 100% probability. The entire statistical probability expressed in a paternity test result is based on what is called Bayes’ Theorem.

All our paternity tests begin with an assumption that there is a 50% chance that the alleged father tested is the biological father and a 50% chance that he is not. The analysis will confirm with utmost scientific accuracy whether or not he is in fact the father of the child.

EasyDNA Switzerland uses 21 genetic markers for all is paternity tests. A match between all genetic markers means the man tested has fathered the child.

Sample results

The results are put together in the simplest way giving our clients the indispensable information they need and the most important aspects of their test.

Our results will clearly show:


  • The details of all parties that have been analyzed
  • The table with the genetic profiles of each individual (showing all 21 genetic markers)
  • The probability of paternity
  • The interpretation of the results

In exceptional cases it may occur that the tested father is the true father yet still have one or even two exclusions (mismatched genetic markers) because of mutations in the father’s DNA. In most cases of one exclusion, the Probability of Paternity will still be above 99.9% although this cannot be guaranteed. Cases of two exclusions may be ambiguous and require further testing of additional genetic markers. Cases of three or more exclusions result will mean the tested father is “excluded” as being the father of the child. This results in a probability of exclusion of 100%.

Fathers closely related?

In cases where the alleged fathers are brothers, their genetic profiles will of course be quite similar or very similar. If you suspect that the alleged fathers might be brothers, we suggest you send the samples of both alleged fathers.
