1. A device for drying blood, and preserving analytes in dried blood samples during storage and transportation comprising:
at least one blood sample carrier comprises a sheet of an absorbent matrix having a uniform pore size, and able to absorb a predetermined amount of liquid per area, thus allowing for recovery of a fixed amount of dried blood sample per area of said absorbent matrix, wherein a calculated area of said sheet of said absorbent matrix is used to store a fixed amount of blood, wherein said sheet of absorbent matrix is punched into two or more cuts, wherein each of the two or more cuts is used in a separate test to increase statistical significance of measurements;
a desiccant layer mounted as an underlayment adjacent to said absorbent matrix, wherein said desiccant layer is a molecular sieve having properties to adsorb water molecules, wherein said molecular sieve is a sodium aluminosilicate compound having a pore diameter of 4 Angstrom;
a box comprised of a top lid and a bottom lid, wherein said top lid and bottom lid are configured to lock to one another to provide an enclosure for receiving said at least one blood sample carrier; and
a plurality of holding areas separated by ridges and further having channels for air circulation within said enclosure for holding said at least one blood sample carrier.
