Abstract: The present invention provides methods for concentrating and pooling liquid suspensions of biological specimens containing analytes of interest in a dry state. The dried biological specimens containing analytes of interest are reconstituted and released from the matrix for subsequent analysis in concentrated form.

Abstract: A blood collection device includes a collection container, a flexible conduit permanently affixed at a proximal end to the collection container, and a needle permanently affixed to a distal end of the flexible conduit. The collection container, flexible conduit and needle can be provided within a package. A method for collecting blood products is also disclosed.

Abstract: A whole blood collection system includes an automated pump/control unit and an accompanying disposable blood set. When combined and connected to a source of anticoagulant, these elements allow automatic priming of the blood set with anticoagulant and automatic collection of anticoagulated blood product according to three different collection modes. The unit's pump and the blood set are specially designed to cooperate during the collection process to assure that the collected product has a precise blood to anticoagulant ratio. During the collection procedure, the pump/control unit automatically collects data relating to the procedure. Additional data specifically identifying components of the blood set, such as the blood collection bag, along with identification data on the donor's registration form may be scanned into the pump/controller unit by a scanner associated with the unit; this facilitates positive sample identification and tracking.

Abstract: A blood donation unit in which a reduced outside diameter phlebotomy needle is employed to minimize donor discomfort. The blood flow if, however, maintained at a flow level similar to that obtained with standard gauge phlebotomy needles by a roller pump which provides a predetermined pressure differential between the ends of the phlebotomy needle. The blood is mixed with a predetermined ratio of anticoagulant immediately after passing through the phlebotomy needle. The ratio of whole blood to anticoagulant is independent of the volume of whole blood collected.
