Calibrating your instruments with reference methods or reference materials allows establishing the metrological traceability of results, as required by ISO 15189 and 17511, as well as by the 2017/746 regulation on in vitro diagnostic medical devices. Having quality control samples whose target values have been determined with a reference method also allows you to verify the accuracy of the measurements.
Available calibrations
- Measurement of glucose by GC-IDMS in serum and calibration solutions with a concentration between 1.6 and 20 mmol/L.
