A fluid sample processing cartridge comprising: a substrate;a sample well formed in said substrate and configured to receive a volume of fluid sample;a closure configured to be selectively placed over said sample well;a deformable fluid chamber supported on said substrate and configured to hold a
1. A fluid sample processing cartridge comprising: a substrate;a sample well formed in said substrate and configured to receive a volume of fluid sample;a closure configured to be selectively placed over said sample well;a deformable fluid chamber supported on said substrate and configured to hold a fluid therein when in an undeformed state and to collapse upon application of an external compression force to expel at least a portion of the fluid from the fluid chamber, said deformable fluid chamber being in fluid communication with said sample well via a channel formed in said substrate;a mixing well formed in said substrate, said mixing well being in fluid communication with said sample well via a channel formed in said substrate, said mixing well comprising a first peripheral wall and a first floor defining a well and a fluid inlet snorkel extending up a side of the first peripheral wall extending from the channel communicating the mixing well to the sample well and terminating below a top edge of the first peripheral wall; anda driven mixing apparatus disposed within said mixing well and constructed and arranged to mix the contents of said mixing well. 2. The fluid sample processing cartridge of claim 1, wherein said fluid inlet snorkel extends up an outer surface of the first peripheral wall and terminates at an opening formed in the first peripheral wall. 3. The fluid sample processing cartridge of claim 1, wherein said sample well comprising a second peripheral wall and a second floor defining a well and a fluid inlet snorkel extending up a side of the second peripheral wall and terminating below a top edge of the second peripheral wall. 4. The fluid sample processing cartridge of claim 1, wherein said mixing well further comprises an exit port comprising one or more openings formed in the second floor, wherein said floor tapers downwardly toward said exit port. 5. The fluid sample processing cartridge of claim 1, wherein said driven mixing apparatus comprises a first impeller rotatably disposed within said mixing well and a gear configured to be drivingly engaged by a mating gear of an instrument into which the liquid sample processing cartridge is inserted and to rotate the first impeller when engaged by the mating gear. 6. The fluid sample processing cartridge of claim 1, further comprising: a lysis chamber containing a plurality of lysis beads, said lysis chamber being formed in said substrate and disposed along the channel connecting said mixing well and said sample well whereby fluid flowing from the sample well to said mixing well will flow through said lysis chamber; anda bead mixer disposed at least partially within said lysis chamber and constructed and arranged to agitate the lysis beads and fluid flowing through said lysis chamber. 7. The fluid sample processing cartridge of claim 6, further comprising: a first optical interface comprising an enlarged portion of the channel connecting said lysis chamber to said sample well; anda second optical interface comprising an enlarged portion of the channel connecting said lysis chamber to said mixing well. 8. The fluid sample processing cartridge of claim 6, wherein said bead mixer comprises: a motor mounted within said substrate; anda second impeller disposed within said lysis chamber and mounted on an output shaft of said motor. 9. The fluid sample processing cartridge of claim 6, wherein said lysis chamber includes a fluid inlet and a fluid outlet and further comprises a mesh filter disposed over each of said fluid inlet and said fluid outlet and configured to retain said lysis beads within said lysis chamber. 10. The fluid sample processing cartridge of claim 1, further comprising: a pressure port formed in said substrate and configured to couple said substrate to an external fluid pressure source; anda channel formed in said substrate connecting said pressure port to said sample well. 11. The fluid sample processing cartridge of claim 1, further comprising: a waste chamber formed in said substrate, said waste chamber being in fluid communication with said mixing well via a channel formed in said substrate;a fluid exit port formed in the substrate, said fluid exit port being in fluid communication with said mixing well via a channel formed in said substrate;a first externally actuatable control valve disposed within said substrate and constructed and arranged to selectively permit or prevent fluid flow from said mixing well to said waste chamber; anda second externally actuatable control valve disposed within said substrate and constructed and arranged to selectively permit or prevent fluid flow from said mixing well to said fluid exit port. 12. The fluid sample processing cartridge of claim 11, further comprising a capture chamber disposed along a channel connecting said mixing well and said waste chamber. 13. The fluid sample processing cartridge of claim 1, further comprising: a passive valve assembly disposed within said substrate and constructed and arranged to be closed and prevent fluid flow from said mixing well when pressure within said mixing well is not higher than a threshold pressure and to open and permit fluid flow from said mixing well when pressure within said mixing well rises above the threshold pressure; anda pressure port formed in said substrate and in pressure communication with said passive valve assembly by a pressure conduit formed in said substrate, wherein when said pressure port is closed, pressure within said mixing well is allowed to reach the threshold pressure that will open said passive valve assembly and permit fluid flow from said mixing well, and when said pressure port is open pressure within said mixing cannot not reach the threshold pressure so the passive valve assembly is closed. 14. The fluid sample processing cartridge of claim 1, further comprising a lance blister associated with said deformable fluid chamber; said lance blister being connected or connectable to the associated deformable fluid chamber and containing a bead retained within the lance blister by a breakable septum, wherein said lance blister is configured to collapse upon application of an external compression force to thereby push the bead through the breakable septum. 15. The fluid sample processing cartridge of claim 1, further comprising an external shroud externally enclosing at least a portion of said cartridge. 16. The fluid sample processing cartridge of claim 1, comprising a plurality of deformable fluid chambers, each of said fluid chambers containing one or more substances selected from the group consisting of a lysis buffer, a wash buffer, an oil, a rehydration buffer, target capture beads, and a binding buffer. 17. The fluid sample processing cartridge of claim 1, further comprising: a first fluid exit port formed in the substrate, said first fluid exit port being in fluid communication with said mixing well via a channel formed in said substrate;a second fluid exit port formed in the substrate; andat least two deformable fluid chambers, one of said two deformable fluid chambers being in fluid communication with said mixing well via a channel formed in said substrate, and the other of said two deformable fluid chambers being in fluid communication with said second fluid exit port via a channel formed in said substrate that is different from the channel communicating the first fluid exit port with said mixing well. 18.
