ISO 15189 Certification and Accreditation Lab Immunodermatology


Certification for a lab is important as proof that a lab is well organized and that the testing is done to the best possible standards. The certification for laboratories throughout the Netherlands is ISO 15189. Until recently, the immunodermatology lab still had an outdated CCKL certification.  In 2020, all departments within the Pathology of the UMCG will be audited online by the Council of Accreditation. Since the immunodermatology lab is now part of the department of Pathology and Medical Biology, we were also audited. The audit went very well. There is always room for improvement, of course, but we have tackled all points together as a department and now we are ISO certified and accredited.

The immunodermatology lab has set up a number of unique tests for the diagnosis of autoimmune bullous disorders. Partly because of this, the UMCG can be proud to be the center for blistering diseases of the Netherlands. The tests are often self-developed and allow very precise diagnosis to be made. Every department of Dermatology in the Netherlands knows that, we receive many requests from national and international. With the ISO 15189 certificate, we demonstrate that our diagnostics meet the highest quality requirements.
