HbA1c 4 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 4 vial kit contains 2 normal and 2 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.
