ABSTRACT:
A pre-determined concentration of stabilized, maturation-arrested porcine reticulocytes in a red blood cell base, useful as a reticulocyte control composition. The composition can be provided in the form of a concentrated reticulocyte composition, to be diluted to a desired final reticulocyte concentration at the time of use. The composition can also be provided in the form of a diluted, ready-to-use control composition. Also included is a method of preparing such a composition, the method involving sequential steps of forming and sedimenting Rouleaux bodies.
