PROCESS AND A METACHROMATIC COMPOSITION FOR EFFECTING A COUNT OF LEUCOCYTES, AND MORE PARTICULARLY OF BASOPHILES

摘要

A B S T R A C TThe invention relates to a process for countingin vitro leucocytes, more particularly non degranulatedbasophils contained in a blood sample which comprises contactof the blood sample to be tested with a reagent containing ametachromate agent, a fixative fox leucocytes and basophils,and an acid present in such proportions that the final pH ofthe sample/reagent mixture is between about 3 and 5.
