[Studies on the manufacture of hematological and cytological specimens using the centrifugation technic].
Centrifugal preparation (Cp) represents a method of creating haematological parameters which, in addition to a qualitative improvement of representing single cells, is suitable to produce reproducible haematological smear preparations. In qualitative and quantitative respect centrifugal preparations will reflect the intravasal conditions better than the common blood smear technique. Further advantages are the concentration of cellular elements and in connection with it the opportunity of finding cells rarely present. With a small amount of work centrifugal preparations enable counting values to be established as well as cytological and cytochemical findings from the venous blood to be obtained. As a result of the test it turned out that the common glass slides cannot be replaced by plastic foils ones without certain disadvantages appearing. First investigations of attempting to represent cells in culture medium as well as analyzing liquors and processing other biological liquids with the help of the centrifugal preparation technique brought unsatisfactory results. Centrifugal preparation provides the possibility of performing pre-programmed haematological examinations beginning with blood collection and ending up in the evaluation by a computer.
