HAEMATOLOGISCHE ZUSAMMENSETZUNGEN ALS REFERENZ FUER DREI POPULATIONEN VON LEUKOCYTEN, VERFAHREN ZU DEREN HERSTELLUNG UND DEREN VERWENDUNG IN GANZBLUTTESTVERFAHREN.

摘要

This invention primarily is directed to a hematology reference control solution, the three separate white cell control portions thereof consisting of three types of fixed red cells of determined size distribution for checking the operation of a particle analyzing instrument, including its predetermined lower and upper threshold settings for each class or subclass of leukocytes. For preparing a human granulocyte analogue, nurse shark erythrocytes are altered and fixed in a chilled solution to simulate in number, size and distribution the granulocytes in human whole blood. Such a granulocyte analogue is useful as a free-standing reference control, for determination of human granulocytes only, or can be comingled with reference controls for lymphocytes and mononuclear cells for use with multi-parameter instruments to give a trimodal leukocyte reference control, which itself can be included in a multiple-analysis hematology reference control, having components for also determining red blood cell and platelet parameters.
