The G7 Automated HPLC Analyzer – HbA1c Variant Analysis Mode uses non-porous ion-exchange high performance liquid chromatography (HPLC) for rapid, accurate, and precise separation of the stable form of HbA1c from other hemoglobin fractions. Analysis is carried out without off-line specimen pretreatment or interference from Schiff base.

blood specimen with Hemolysis & Wash Solution, and then injects a small volume of the treated specimen onto the HPLC analytical column. Separation is achieved by utilizing differences in ionic interactions between the cation exchange group on the column resin surface and the hemoglobin components. The hemoglobin fractions (A1c, A1b, F, LA1c,

Blood Collection and Handling – Dried Blood Spot (DBS)

Blood Spot (DBS)? Dried Blood Spots (DBS) are whole blood collected on filter paper and dried. They are made directly from the client’s whole blood. DBS are used for re-testing at a reference laboratory, which may be part of your country’s External Quality Assessment plan. Testing site results are compared to reference laboratory results.
