In the calibration laboratory at INSTAND e. V. we determine target values for control materials that are used to assess lab results as part of external quality assurance (EQA tests).
To determine these target values, we use analytical methods that guarantee the highest level of accuracy and precision of the measurement results.
These so-called reference measurement procedures are internationally recognized as calibration methods and are listed with the Joint Committee for Traceability in Laboratory Medicine (JCTLM). In accordance with the guideline of the German Medical Association, target values are determined using the reference measurement procedures for around 30 analytes used in laboratory medicine.
For these parameters, the lab also offers, as a calibration service, the certification of control and calibration materials used by manufacturers of analysis equipment for metrological traceability. The reference laboratory at INSTAND e. V. is a calibration laboratory that is accredited by the German Accreditation Body (DAkkS) in accordance with ISO standards 17025 and 15195.
The lab is active on national and international committees (DIN, ISO) and participates in international comparative measurements for reference laboratories (IFCC-RELA survey and IFCC-HbA1c Network) .
The calibration lab at INSTAND e. V. also focuses on research and development for promoting standardization and metrological traceability of measurement results to SI units in laboratory medicine. New reference measurement procedures are continuously being developed in cooperation with international working groups from the International Federation of Clinical Chemistry (IFCC) and national, metrological institutes.
Reference measurement methods
Reference measurement methods are analysis procedures of the highest hierarchical level of metrology. They enable target values to be determined with the highest level of accuracy and precision.
