KRÁLOVÁ, Michaela
The topic of thesis are reasons for discarding blood donors. The aim of this thesis is to evaluace the amount of discarded blood donors and the reasons for elimination in 2015 and 2016, further implementation of pre-sampling and post-sampling tests in the Blood Bank Department of the Hospital ČB, Ltd. In the theoretical part I attend to important events in the history of transfusion medicine. Next I deal with criteria for receiving blood donors, evaluation of the blood donors and ways, amounts and frequency of blood collections. The important part of my thesis are the reasons for discarding blood donors, which are divided into temporary and permanent. There are registers, in which these donors are registered. In the methodological part I attend to pre-sampling and post-sampling tests, which are performed in the Blood Bank Department of the Hospital ČB, Ltd. At pre-sampling laboratory measurement of hemoglobin amount on HemoCue 201+ is performed. For new blood donors the blood group orientation is examined on the slide. Donors plasma, platelets or in case of chylozity blood at the last sample hematokrit is examined. Further examination post-sampling test, which are include tests of infectious markers and imunohematology. For examination infectious markers are of service analyzer Architect, tests make on this analyzer are: Ab anti HCV, Ag and Ab HIV, Ab against Treponema pallidum and HBsAg. Immunohematology tests are examination with a dispenser Qasar and imagine analyzer Duet Reader. These two devices are jointly involved in the testing of AB0 blood group and RhD, screening of irregular anti-erythrocyte antibodies and examination of a group of Rh Kell. In 2015 there were 15 048 blood donors and 360 women and 306 men were discarded. In 2016 there were 15 788 blood donors and 286 women and 211 men were discarded. The most blood donors were discarded because of unsufficient amount of hemoglobin.
