Abstract
Method for the automatic analysis of a blood sample in which: an analysis solution containing the blood sample, a diluent, and at least one compound to lyze the erythrocytes; at least one compound to stabilize the haemoglobin in the form of a chromogenic complex, is formed in a single dilution and analysis tank, the haemoglobin level is measured in this analysis solution by spectrophotometry in the tank after the lysis of the erythrocytes; and an appropriate quantity of this analysis solution is taken from the tank on which a leucocytic differentiation is carried out by an optical elements characterized in that the analysis solution also contains at least one compound to protect the leucocytes, allowing the distinguishing of at least four main leucocyte sub-populations. A haematological analysis apparatus for the implementation of such a method is disclosed.
