Process for the preparation of a preservable suspension of leucocytes for their examination

摘要

The invention relates to the field of haematology and its subject is a process for the preparation of an aqueous suspension of leucocytes. The process of the invention is characterised in that a very small quantity of blood is brought into contact with an excess quantity of a solution of acetic acid CH3COOH supplemented with a surface-active product, the resultant haemolysis being stopped by the addition of a solution of trisodium phosphate Na3PO4 in a quantity which is necessary to bring the medium to pH 7.
