METHOD FOR THE DIFFERENTIAL DETERMINATION OF POPULATIONS OF LYMPHOIDS AND MYELOIDS OF LEUKOCYTES AND FOR MEASURING HEMOGRAM VALUES, MULTI-PURPOSE ISOTONIC DILUENT AND METHOD FOR THE DETERMINATION OF LEUKOCYTES AND HEMOGLOBIN IN BLOOD

摘要

THE PRESENT INVENTION RELATES TO A METHOD FOR THE DIFFERENTIAL DETERMINATION OF POPULATIONS OF LYMPHOIDS AND LEUCOCYTE MYELOIDS, AND ALSO FOR THE MEASUREMENT OF HEMOGRAM VALUES. /P P DEPENDING ON THE INVENTION, A COMBINATION IS USED. ISOTONIC DILUENT COMPRISING A MIXTURE OF AN AQUEOUS SOLUTION OF ANESTHESIC COMPOUNDS COMPRISING DERIVATIVES OF 4-AMINO-BENZOIC ACID ESTER, ORGANIC BUFFERS AND GERMICIDES AND WHICH IS ADJUSTED TO A PH OF 7.1.1 WITH A SOLUTION OF SODA OR HYDROCHLORIDE AND OSMOLALITY OF 3205MILLIOSMOLES PER KILOGRAM WITH SODIUM SULPHATE AND SODIUM CHLORIDE, AND A LYSING REAGENT CONSISTING OF A MIXTURE OF AN AQUEOUS SOLUTION OF AT LEAST ONE QUATERAMMOL HAVING TENSIO-ACTIVE PROPERTIES AND A CYANIDE OF AN ALKALINE METAL HAS AN EFFECTIVE RANGE OF CONCENTRATION TO GIVE HISTOGRAMS OF THE TWO VOLUMES OF THE LEUCOCYTES. /P P THE INVENTION APPLIES IN PARTICULAR TO COUNTING SYSTEMS AUTOMATIC P FOR THE STUDY OF BLOOD.
