Preliminary comparative study of HBA1c measurement by IEX-HPLC Bio-Rad in dried blood spot vs. whole venous blood.

HBA1c testing is a health indicator for pre-diabetes identification or diabetes detection and follow-up. Simplifying collection and transport of blood samples for HBA1c measurement remains of great interest. Capillary dried blood spots (DBS) sampling has been proposed as a potential alternative to classical whole blood (WB) venipuncture, however, international analytical and clinical validation of DBS use is necessary before implementation.
