Laboratory Comparison Tests

Custom-Made Comparison Tests

Special request external quality control tests offered for accredited laboratories mean inter-laboratory comparison tests independent of time and content (Quick-Turn Proficiency Testing). In this test group, the laboratory determines the contents it needs (eg test parameters, matrix, analysis method) and shares this content with the comparison test provider. If the requested content is found suitable for the test cycle, a suitable date is determined for the participant. Afterwards, the test is organized and the comparison test report containing the Z score and other statistical results is presented to the participants.

Special request external quality control tests are performed with the participation of at least 2 or 3 accredited laboratories. When the test request form is shared with the test provider, this information is shared by the test provider with other participating laboratories and the test cycle is performed with all participating laboratories.
