HbA1c 24-Vial Liquid Controls

The liquid Hemoglobin A1c control is a two level control with defined levels between 4.5% - 6.0% (Normal, Level 1) and between 9.0% - 14.0% (Abnormal, Level 2). They are intended as a quality control material for analytical methods including ion exchange HPLC, immunoassay and boronate affinity for quantitation of HbA1c. The controls are in glass vials with screw top caps.

Our 24 vial kit contains 12 normal and 12 abnormal level controls. Each vial contains 1.0mL with a typical hemoglobin concentration of 14g/dL. The closed vials when stored at 2° - 8°C have an expiry date of 30 months from production. The vial once opened is stable for at least 30 days when stored closed at 2° - 8°C.

The Level 2 Control is produced by In Vitro Glycation

The Level 2 extendSURE™ HbA1c control is produced by a process of controlled in vitro glycation of non-diabetic blood. This means there is not a reliance on sourcing blood from diabetic subjects with high HbA1c levels, and it also means that levels of up to over 20% can be produced in significant quantities. It also avoids the potential ethical issues relating to obtaining blood from a patient with a clinical condition.
