| Low - whole blood sample with HbA1c concentration of 5.3% measured by Premier Hb9210. High - whole blood sample with HbA1c concentration of 7.6% measured by Premier Hb9210. TBIL - total bilirubin. TG – triglycerides. CHOL – cholesterol. Vit C - vitamin C. Glu - glucose. “/” - not performed. The bold results show relative bias > ± 7% (calculated by NGSP units). Relative bias > ± 7% was considered clinically significant (NGSP criterion). | ||||||||
