title: Storage, retrieval, and inventory control of donor red cells in liquid nitrogen.
abstract: A system of identification and inventory control of donations and aliquots of human blood stored in liquid nitrogen is described. It is simple and easy to operate. Up to five adequate samples can be obtained from each donation at discrete intervals without the need to recover the main donation or, as is so often the case, the only single aliquot available.
