New Direct HbA1c Reagent Application for Vital Diagnostics Envoy500 analyzer

Pointe Scientific, Inc. has introduced an application for the direct measurement of HbA1c on the Vital Diagnostics Envoy500 analyzer.

This unique single-channel immunoturbidimetric assay is fully automated, requires no manual sample preparation, no separate total hemoglobin measurement and no additional calculations.

Non-specific binding of total hemoglobin, both glycated and non-glycated to latex particles is employed in the first reaction. Specific antibodies used in the second reaction result in agglutination of only HbA1c bound latex particles. The absorbance of the agglutination is measured at 600 to 660nm and the %HbA1c concentration is determined using calibrators with known %HbA1c values.
