Important of Accreditation for a DNA Testing Laboratory

Accreditation is important for any company offering DNA testing. This is because as a client seeking the help of anything from an ancestry test to a paternity DNA test, you need to have some kind of guarantee or reassurance that your DNA test is being carried out in a facility that is suitable to carry out such tests. After all, doing a DNA test can be a very difficult choice, of which results can indeed change one’s life. homeDNAdirect only works with fully accredited laboratories.

Accreditation: What is it?

An accreditation is essentially an act by which a company or laboratory gets granted some type of recognition for excelling at what it does. To be able to receive an accreditation, a DNA testing facility must meet certain very high standards and only after having met these can the laboratory be given an accreditation certificate. Our main laboratory accreditation is ISO 170 25

The two above accreditations are the most renowned and prestigious accreditations for a DNA testing laboratory. For you, as a potential client, these accreditations translate into a certification or assurance of competence in the test the laboratory is offering. ISO is short for the International Standards Organization; it is one of the most important accrediting bodies worldwide and the ISO 17025 certification is specifically created for DNA testing laboratories. To be able to get this accreditation the laboratory has to excel in many areas including:

  • All internal procedure that entail quality control management
  • Technical and analytical abilities of staff and equipment used
  • All sample handling

It is not only a matter of receiving an accreditation. In fact, to ensure the laboratories are consistently sticking to all quality guidelines and parameters set by ISO, they get periodically awarded. If at any stage a DNA testing facility that has been awarded the ISO 7025 certificate is found during an audit to not be fully compliant, the certificate may be withdrawn. ISO 17025 does carry many similarities to the ISO 2009, but the 17025 accreditation is tailored for laboratories.

Our 21 Genetic marker profile  

homeDNAdirect Ireland uses a 21 genetic marker profile for its DNA paternity testing. Using this 16 marker profile we are able to provide extremely conclusive paternity test results. Paternity testing is normally carried out between:

  • Putative / alleged father
  • Mother
  • Child

In a laboratory analysis in which we have access to all the three above samples, we can provide extremely accurate results. The likelihood that the alleged father is the biological father of the child tested, we call a probability of paternity. This is because paternity testing essentially does involve a statistical aspect where we determine how likely it is that the tested father is the biological father of a child when compared with any random individual within a given population.

If the alleged father has the same exact genetic markers as the child, then we can provide a probability of paternity of 99.9% (without the mother’s DNA sample) and a probability of paternity of 99.99% (with the mother’s sample).
