Abstract
Freshly obtained blood samples are deposited into a device that contains blood sample carriers, each of the carriers is designed to hold a fixed amount of blood and allow excess blood sample to flow through and be discarded. A desiccant within the blood sample carrier aids with the drying of the blood and the discarding of the excess sample blood. The device is stored/transported within a modified atmosphere package comprised of an impermeable sealable bag and an oxygen scavenger compound for removing oxygen from the bag.
Claims18
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.

- and
- at least one holding area within said enclosure for holding said at least one blood sample carrier;
- and
- a modified atmosphere container comprised of an impermeable bag and containing therein a bag of an oxygen scavenging compound.
