Accreditation is an international procedure used to determine and confirm the technical competence of a laboratory in a particular field. The accreditation process is based on a set number of criteria amd procedures designed specifically to determine the technical competence of the laboratory to produce an accurate DNA test.

The accreditation process is normally conducted by specialist technical assessors that are external to the laboratory. Through a rigorous evaluation process they will check all the processes that affect the production of the test or the calibration of the data. The laboratory accreditation specifically aims to confirm the laboratory\’s ability to produce over and over again accurate and precise results.

At easyDNA all our DNA tests are performed by an internationally accredited laboratory. For more information about the laboratory and its accreditation visit the our laboratory section.


The National Association of Testing Authorities (NATA) accreditation provides a means of determining, recognizing and promoting the competence of facilities to perform specific types of testing and provides formal recognition to competent testing facilities, thus providing a ready means for customers to identify and select reliable testing services. To maintain this recognition, laboratories are re-evaluated periodically by NATA to ensure their continued compliance with requirements, and to check that their standard of operation is being maintained. The laboratory is also required to participate in relevant proficiency testing programs between reassessments, as a further demonstration of technical competence. NATA is the most difficult Accreditation for a Parentage Testing Laboratory to attain due to its rigorous quality and security requirements.

ISO 17025

ISO 17025 is the global standard for the technical competence of calibration and testing labs. As a laboratory accredited to ISO 17025:2005, our Laboratory has incorporated an overall system for technical and quality management. This results in superior laboratory practices and customer service. We have implemented the ISO 17025 quality system in our Laboratory and are fully accredited as of April 2007.


The A2LA is the largest multi-discipline laboratory accreditation system in the United States and is recognized by Accreditation Bodies in the European Union and other International Communities. A2LA accreditation imposes stricter requirements than ISO 17025: 2005 certification alone, particularly focusing on technical competence, traceability of measurements and the overall proficiency of the laboratory.


We are one of only a handful of DNA testing laboratories actually accredited by the AABB  (previously known as the American Association of Blood Banks). Accredited laboratories have passed a rigorous review and inspection of their testing processes and laboratory to insure that tests are being done accurately and thoroughly. Accredited laboratories also participate in proficiency tests and are re-inspected bi-annually.

Accuracy of our testing

When issuing the result of a DNA paternity test, the alleged father will be confirmed as the true biological father of the child only if all the 20 genetic markers analysed do match those of the child (the 21st marker is analysed to confirm the sex of the individual tested) and is referred to as a \’no exclusions\’ situation. When the testing involves the mother, alleged father and child, we guarantee that our DNA paternity tests will generate a probability of paternity in excess of 99.999% when the paternity is confirmed. When it is a case of exclusion the probability of paternity will be 0% (or else a 100% exclusion).

In cases where the paternity test includes only one parent and the child, the resulting probability is in most cases greater than 99.99%, although an exact mimum probability of parenthood as per above cannot be determined in advance.

Such extremely high probabilities mean that you can have the peace of mind that the test will confirm whether the alleged father is the true biological father or not.

Sample DNA test results

In order to facilitate understanding our results, we have provided a sample to show you what a paternity testing result will look like. On the same page you will find comprehensive information on how to interpret the results you obtain.
