BLOOD DILUENT FOR USE IN ELECTRONIC BLOOD CELL ENUMERATION AND CALSSIFICATION, DETERMINATION OF HEMOGLOBIN CONCENTRATION AND ITS COLLECTIVE INDICATIONS AND PLATELET PARAMENTERS IN A UNIQUE BLOOD SAMPLE

摘要

A multi-purpose blood diluent especially suitable for use in electronic enumeration and sizing of blood cells, determination of hemoglobin concentration and their collective indices and platelet parameters in a single blood sample by means of suitable electronic instrumentation. The diluent is characterized as azide-free and capable of affording accurate, reproducible hematological test results from the said suitable electronic instrumentation. The diluent employs a chelating agent which functions as a bacteriostat and fungistat agent to prevent adverse growth of micro-organisms and a compatible stabilizing agent to maintain desired morphology of red blood cells and an inorganic metallic sulfate for suppressing turbidity caused by abnormal globulins and/or high leukocyte counts which are encountered in certain blood samples. Because of the capability for use of the diluent in platelet determinations by the instrumentation, the diluent further is free of detergent action which would cause bubbles capable of interfering with the enumeration of platelets by the instrumentation. A modified and adjusted embodiment of the diluent enables its use in veterinary laboratory testing applications.
