Representation of a cord blood bag including small segments that are unmistakably linked to the principal transplantation product. Samples contained in the segments can be used for specific tests with 1 segment still remaining for additional quality control assays to be performed at the transplantation center. Such tests may include assays for transmissible diseases (either infectious or genetic markers), identity tests (HLA and ABO), and efficacy tests (CFU and functional flow cytometry).
