Abstract
The present invention relates to a hematology control product for automated hematology instruments containing an aqueous solution of at least one blood cell analog, an absorbance agent in an amount sufficient to simulate a hemoglobin concentration, and a stabilizing agent in an amount sufficient to stabilize the size of the blood cell analog when the control product is subjected to temperature ranging from -15.degree. C. to 45.degree. C. The control product does not require controlled temperature storage for product stability. In addition, a novel method of using a hematology control product is provided wherein the control product contains a single blood cell analog and is used to simulate both red blood cells and white blood cells on an automated hematology instrument.
