Abstract

The present disclosure relates to devices, methods and kits for blood sample separation and analysis. More particularly, the disclosure relates to devices, methods and kits that rapidly separate a blood sample into uniform solid and liquid phases in a sealed environment. A specific example includes a device with a door coupled to the housing, a blood sample separation medium, a mesh material and a desiccant. In one example, the blood sample separation medium is disposed between the housing and the mesh material, the desiccant is coupled to the door, the desiccant is distal from the mesh material when the door is in a first open position, and the desiccant is proximal to the mesh material when the door is in a second closed position.
