Abstract :
[en] Whole blood analysis is an emerging trend in the field of bioanalysis. We developed a fast and simple protocol to extract and analyze
a peptide, hepcidin, from whole blood. Sampling and extraction were carried out using volumetric absorptive microsampling
(VAMS), a novel blood collection method that allows the sampling of a known blood volume independently from hematocrit. The composition of the extraction medium was optimized using an experimental design to get the most intense signal of hepcidin, considering different organic solvents and acidic additives.
