State of scientific knowledge and economic prerequisites determined the selection of the optimum methods for the necessary parameters in standardizing haematologic methods. Concerning the methods of counting, measuring and staining in the haematologic laboratory, we have to do above all with so-called conventional methods with an expenditure of work considerable in most cases. In the single steps necessary for obtaining a laboratory result the physician in a clinic or outpatient department essentially participates particularly in such cases when EDTA venous blood is applied. It is especially referred to the advantage of EDTA venous blood for taking blood samples for haematologic parameters compared with the taking of capillary blood which has a high rate of error. Apart from the common efforts of physicians in clinics or out-patient departments and laboratory physicians to obtain reliable results of the findings, the use of an improved technique (particle counters, dilutor, automatic picture analysis among others) as well as further proceedings of standardization (dye for panoptic staining and others) will achieve this aim.
