Our laboratories are committed to providing pathology services of the highest quality. The quality of results is of fundamental importance, and the laboratories operate to stringent technical and administrative standards.

Internal quality assurance is achieved by strict adherence to standard operating procedures for all analytical processes. TDL Group laboratories participate in recognised National External Quality Assessment Schemes; these schemes are subscribed to by NHS and private laboratories.  The U.K. Accreditation Service (UKAS) provides accreditation to the internationally recognised ISO 15189 Medical Laboratories: Requirements for Quality and Competence standard. Results are subjected to strict internal and external quality control.
