Abstract
A reagent for measurement of the haemoglobin and determination of the leukocytes in a blood sample is provided. This reagent comprises at least one detergent of the cationic type; a compound of the glycoside type, and in particular a saponin; at least one inorganic salt and/or an osmotic and/or leukoprotective agent; and an organic and/or inorganic buffer which can adjust the pH of the agent selectively, either to a substantially neutral value, e.g. pH between 5 and 8, or to a basic value, e.g. pH between 8 and 12. The reagent can be used in haematological analyses in human and veterinary medicine.
