Why laboratory accreditation is important?
Laboratory accreditation is a means of assuring quality in laboratory services. The process involves assessing the laboratory's technical competence, management system, and the quality of results produced. Accredited laboratories are required to operate according to recognized standards and guidelines, ensuring that the laboratory is competent and capable of delivering accurate and reliable results, protecting the laboratory, customers, and the public.
Furthermore, organizations will not spend time and money on testing and approvals in each country in which they sell. Recognized international standards allows organizations from all over the world to more easily sell their products and services in other countries as global standards equate to international acceptance of test data.
