EKF Stanbio Chemistry GSP LiquiColor diabetic biomarker test

EKF Diagnostics has introduced a diabetic biomarker test that provides a 2-3 week indicator of average blood glucose. The Stanbio Chemistry Glycated Serum Protein (GSP) LiquiColor test closes the information gap between daily blood glucose testing and the 2- to 3-month HbA1c reading. This means it serves as an accurate intermediate marker of glycaemia in instances where HbA1c may be of limited value, such as pregnancy, reduced RBC lifespan and hemodialysis.

The assay, based on a double enzymatic degradation method, is said to provide better specificity and accuracy compared to the older non-enzymatic fructosamine NBT method. This is because the test utilises the specificity of fructosyl-amino oxidase to eliminate inaccuracies caused by non-glycated protein reducing substances which significantly interfere with the NBT fructosamine method.

Available as a liquid-stable kit and calibrator, the open-channel enzymatic test is suitable for use on a variety of clinical chemistry analysers, with onboard stability of up to four weeks. It is also both FDA approved and CE marked.
