In one embodiment of the present disclosure, the apparatus includes a main body, lancet carrier or hub, lancet, lancet trigger, capillary tube, and sample compartments for collecting and storing dried blood and other bodily fluids. The lancet hub supports a lancet and provides for moving the lancet longitudinally between a first retracted position and a second extended position. The device includes a capillary tube having an internal diameter sized to draw and retain fluid from a contacted source using capillary action. The main body of the apparatus further includes a sample compartment for holding sampling and storage materials. In at least one embodiment of the present disclosure, the sample compartment can be accessed by lifting sample compartment lid. Also included is a new “fan” or “daisy” shaped collection material format for use in collecting and preserving samples. ## Claims ### Claim 1 A sampling and storage device for biological fluids comprising: a body comprising: two or more structural components that can at least partially be attached and detached from one another and can form an open and a closed configuration, having a top portion and a bottom portion in the closed configuration, wherein the components form one or more interior cavities when in the closed configuration; a carrier that is disposed on the top surface of the top portion, wherein the carrier extends from one edge of the body to the opposing edge and comprises a channel; a capillary tube contained in the channel of the carrier and extending from an exterior of the device to a fluid reservoir and in fluid communication with the one or more interior cavities; one or more collection compartments formed in the one or more interior cavities and in fluid communication with the capillary tube; one or more pieces of sampling material placed within the one or more collection compartments and in fluid communication with the capillary tube; and a desiccant contained within the cavities in vaporous communication with the sampling material, and suitable for drying a collected sample and maintaining low humidity in the device; and a mechanism for sealing the device from the environment after use. ### Claim 2 (depends on 1) The device of claim 1, wherein the sampling material is a solid support comprising nylon, polypropylene, polyester, rayon, cellulose, cellulose acetate, mixed cellulose ester, glass microfiber filter, cotton, quartz microfiber, polytetrafluoroethylene, polyvinylidene fluoride, filter paper or a combination of any thereof, or one or more sheets of absorbent material. ### Claim 3 (depends on 1) The device of claim 1, wherein the sampling material, the capillary tube or both comprise an anticoagulant. ### Claim 4 (depends on 1) The device of claim 1, wherein the sampling material comprises a detergent, a chelator, a pH modulating chemical, an enzyme inhibitor, a denaturant, or a combination thereof. ### Claim 5 (depends on 1) The device of claim 1, wherein the biological fluid is whole blood, plasma, serum, urine, saliva, cerebrospinal fluid, a tissue culture supernatant, bronchoalveolar lavage, synovial fluid, a tissue extract, tear, or a skin washing. ### Claim 6 (depends on 1) The device of claim 1, further comprising one or more identification mechanisms. ### Claim 7 (depends on 6) The device of claim 6, wherein the identification mechanism is one or more bar code tags, one or more RFID tags or a combination thereof affixed to the device. ### Claim 8 (depends on 1) The device of claim 1, further comprising one or more identification mechanisms attached to the sampling material. ### Claim 9 (depends on 8) The device of claim 8, wherein the identification mechanisms are one or more barcode tags, RFID tags, or a combination thereof. ### Claim 10 (depends on 1) The device of claim 1 wherein the sealing mechanism is selected from a sticker placed over the outside opening of the capillary tube, a plug placed within the capillary tube, a movable door or slide that can be positioned to cover the capillary opening, pinching or twisting the capillary tube so that it is sealed, and replacing the capillary tube containing structural component with a structural component not containing a capillary tube. ### Claim 11 (depends on 1) The device of claim 1 further comprising a lancet device within the channel of the carrier that is effective to cause a small wound in the subject to create a blood flow for collection in the device. ### Claim 12 (depends on 1) The device of claim 1 wherein the sampling material comprises a central disk from which radiates a plurality of protrusions, wherein each protrusion contacts only the central disk and does not contact any other protrusion, and wherein the plurality of protrusions and central disk substantially define a fan-shape. ### Claim 13 (depends on 1) A method of sampling and storing a biological fluid from a subject for testing comprising: contacting a biological fluid of the subject with the end of the capillary tube of the device of claim 1 effective to draw the biological fluid into the one or more interior cavities and into contact with the sampling material; drying the biological fluid absorbed into the sampling material; and storing the dried biological material in the device. ### Claim 14 (depends on 13) The method of claim 13, further comprising shipping the device containing the dried biological sample to a location remote from the collection site for testing. ### Claim 15 (depends on 13) The method of claim 13 wherein the sampling material is removed from the device for testing. ### Claim 16 (depends on 13) The method of claim 13, wherein at least a portion of the sampling material comprises a chemical test reagent that reacts to a characteristic or component of a biological fluid. ### Claim 17 (depends on 16) The method of claim 16 wherein the reaction results in a color change.
