Background: Microsampling techniques have several advantages over traditional blood collection. Dried blood spot (DBS) sampling and blood collection with heparinized capillaries are the standard techniques. Volumetric absorptive microsampling (VAMS) is a novel technique that collects a fixed volume of blood by applying an absorbent tip to a blood drop. In the present study we explored the feasibility of HbA(1c) monitoring with VAMS sampling at home and analysis in the laboratory. Methods: Diabetic patients were enrolled in this study during consultation with the endocrinologist. A venous (adults) or capillary (children) sample was taken for immediate HbA(1c) analysis. DBS (n=1)and dried VAMS (n=2) were collected at home and sent to the labo...
