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.
