Abstract
Combination and method for mixing a blood sample and an anticoagulant within a collection tube and for then capturing, removing and discarding the mixing element without danger of direct contact between the blood sample and the technician. The full combination includes a blood collection tube, at least one resilient end cap for the tube having a cavity which extends well beyond that tube when the cap is in place, a magnetic element slidable within the tube and receivable in the cap, and a magnet for shifting the magnetic element. After being directed into the cap following a mixing operation, the blood-covered magnetic element may be held within the cavity by finger pressure on the cap and discarded along with the cap.
