GCMS – Glucose

< Go back to Reference Measurement Services page

Reference values provide accurate measurement of Glucose for assessment of traceability to the SI unit for routine diagnostic methods used in patient monitoring. Metrological traceability of methods is a requirement of ISO/IEC 15189 accreditation and returned EQA results should be scored against the Reference Value where available.

ID-GCMS values are assigned to all EQA material for Glucose using the modified NIST definitive method, allowing a “true” assessment for accuracy of participant returned results to the Reference method for each distribution. This service is also available to external clients in the post-marketing vigilance of the EU Directive 98/79/EC.
