Abstract
Hematologic control and calibration standards are disclosed which are essentially plasma-free. These controls are prepared by the suspension of red blood cells in an appropriate buffer containing a stabilization effective amount of disaccharides, and other optional ingredients. Control and calibration standards prepared in the foregoing manner are suitable in the control and calibration of hematology analyzers for the following parameters: white cell count, red cell count, hemoglobin, hematocrit and the common derived parameters (i.e., mean cell volume, mean cell hemoglobin and mean cell hemoglobin concentration). The addition of platelets to the foregoing suspensions is also contemplated to provide a control for platelet parameters.
