ABSTRACT:
Systems and methods for collecting blood substantially free of undesired matter assure that accurate crossmatching and typing of cellular blood components can be done prior to transfusion, even though the cellular components are collected and stored in different containers. The blood containing the undesired matter is collected in a blood collection container. The blood collection container includes a tube that is sealed for retaining samples of the collected blood for later analysis. The collected blood is conveyed out of the blood collection container for removal of undesired matter. The blood substantially free of the undesired matter is collected in a separate transfer container for storage. The distal end of the sealed tube containing the blood samples is attached to the transfer container, while the other end of the sealed tube is disconnected from the original blood collection container. This leaves the sealed tube and, with it, the retained blood sample, attached only to the transfer container, which now holds blood substantially free of undesired matter. Using the systems and methods, direct traceability can be assured between red blood cells made substantially free of white blood cells for transfusion and the donor from whom the red blood cells were obtained.
