Abstract: A suspension composition for a hematology analysis control particularly useful for preserving relevant detectable characteristics of blood cells for a prolong stability period. The suspension may include at least one polysaccharide, which may include or derive from chitosan and/or chitin, as a stabilizing agent.

Abstract: A composition (and associated methods) including a plurality of treated red blood cells for simulating reticulocytes, and particularly an immature reticulocyte fraction, of whole blood when processed as a sample in an automated analyzer capable of detecting reticulocytes. A method for making the composition or other simulated reticulocyte may include steps of contacting a suspension of a plurality of red blood cells each having a membrane in an initial state that surrounds an interior volume of a cell with an effective amount of a hypertonic permeabilizing solution including dimethyl sulfoxide and a hypotonic loading agent delivery solution including a loading agent, for a sufficient time to form a plurality of pores in the membrane, for permitting the loading agent to enter into the interior volume of the cells.

Abstract: Hematology control compositions and systems used to measure a plurality of parameters in a blood sample are provided. The hematology control compositions are particularly useful as a control for multi-parameter, automated instrument systems. The control compositions comprise a reticulocyte component, a white blood cell component, a red blood cell component, a nucleated red blood cell component, a platelet component and a reticulated platelet component. Methods of making and using the control compositions are also provided.
