[The significance of morphologic-hematologic methods].

Abstract

A survey is given on the value of the haematologo-morphological examination methods, especially the differential counting of leucocytes, the smear of a concentrate of leucocytes and the cytomorphological judgment of the bone marrow. None of these methods is suitable for the search for cases in the sense of a preliminary diagnosis. This is also of importance especially for the differential counting of leucocytes. However, with aimed methods of proceeding these methods are of great diagnostic value, so that they may be very much in front in a graduated diagnostic program. The diagnostic evidence of a cytomorphological preparation of the bone marrow must highly be estimated concerning a situation of deficiency of iron, a diffuse or small nodular metastasizing of the bone marrow or lesion of the bone marrow by exogenic factors.
