Laboratories

Laboratories can demonstrate their traceability to the IFCC Reference Measurement Procedure by participation in the certification programme. Logistics depend on instrument type and geography. For specific information, please contact c.siebelder@skbwinterswijk.nl

Under the button “Certified Laboratories” you will find the list with certified laboratories.

Criterion is a Total Allowable Error of 5 mmol/mol at an HbA1c concentration of 50 mmol/mol with a risk level of 2σ. The performance comes with a classification: if TE is ≤ 3.3 bronze, ≤2.2 silver and ≤1.1 gold. If TE> 5 mmol/mol the classification is “IFCC criteria not met”. All participants receive a certificate of performance including their classification.
