Table 1 Precision study of HbA1c by both techniques

From: Method comparison of Particle Enhanced Immunoturbidimetry (PEIT) with High Performance Liquid Chromatography (HPLC) for glycated hemoglobin (HbA1c) analysis

  Method Mean Lower limit and upper limit SD CV%
Normal control HbA1c HPLC 5.4% 4.6–5.8% 0.21 3.8%
PEIT 5.5% 4.1–6.0% 0.11 2.0%
High control HbA1c HPLC 9.6% 8.8–10.0% 0.38 3.9%
PEIT 9.7% 9.76–13.6% 0.23 2.3%
