Examination of Cellular Elements in the Cerebrospinal Fluid on the Analyser Sysmex XE-5000 by Method of "Body Fluid".
Davídková, Jana ; Fátorová, Ilona (advisor) ; Pešková, Eliška (referee)
Cerebrospinal fluid is examined using a variety of methods, which also include determining the number and type of each cell. Now the method of the first choice to determine the cellular elements is a microscopic method. This determination, however, can also be done using the analyzer method, which is not yet so widespread. The aim of my thesis was to compare these two methods and determine whether the examination of cerebrospinal fluid on the analyzer Sysmex XE-5000 in the "Body Fluid" mode can replace commonly used microscopic methods. To this purpose, we gathered the laboratory data measured by using both these methods. These data was compared, evaluated and statistically processed. The resulting data suggest that the values measured on the analyzer Sysmex XE-5000 are more accurate than from microscopic determination, especially at highly cell samples of cerebrospinal fluid. To this end, we came evaluation of Bland-Altman graphs and comparison graphs with marked of limits of physiological oligocytosis. For checking of the accuracy of measurements, we verified the repeatability of the analyzer for the values of leukocytes and erythrocytes, coefficients of variation corresponding to the values specified by the manufacturer's documentation. We also investigated the stability of samples of...

Monitoring of blood counts parameters during the therapy in patients with myelodysplastic syndrome
Sochorová, Lenka ; Fátorová, Ilona (advisor) ; Vrbacký, Filip (referee)
Blood counts belongs among basic examination methods in hematology laboratory. It is used to determine the basic parameters of leukocytes, erythrocytes, hemoglobin, hematocrit and platelets. The goal of study was to determine which blood counts have changed during the treatment of patients with myelodysplastic syndrome using immunomodulatory drug lenalidomide. Analysis of blood samples were performed on the Sysmex XE-5000. The selected blood counts parameters were evaluated in two periods - before the beginning of the treatment and during the treatment. The final blood counts showed increasing concentrations of hemoglobin and decreasing platelet values; other blood count parameters have not changed significantly. The evaluated blood counts changes could be used to determine the efficiency of the treatment and the transfusion therapy could be stopped based on these results.
