Theoretical and practical knowledge of pre- analytical phase and blood sampling among students of laboratory medical diagnostics

ABSTRACT The preanalytical phase encompasses all processes that take place from the initial time when the doctor requests a search to the point when the sample is ready for analysis which includes patient identification and preparation, collection and sample handling. Most errors occur in pre-analytical phase (46- 68%), which is the longest and most critical part of the laboratory process. AIM: The aim of this study was to examine and present theoretical and practical knowledge of the preanalytical phase and blood sampling among students of laboratory medical diagnostics. MATERIALS AND METHODS: The examination was conducted through a questionnaire on undergraduate and graduate students of the laboratory medical diagnostics study. Students responded by answering an anonymous questionnaire of six short laboratory questions about the preanalytical phase and the degree of theoretical and practical knowledge of phlebotomy studies. RESULTS: On the first question whether they are familiar with the preanalytical phase of the laboratory process, 134 of 149 students answered yes (90%) and 15 students answered no. To the question of evaluating preanalytical phase, 27(18%) students answered that their knowledge was not well, 93 (62%) students answered good, and 29 (19%) of them said that they were excellent. 44 (30%) students said that they had perfected venous and capillary blood sampling skills during the study program, and 105 (70%) say that they did not. At 72 students (45.6%), theoretical and practical knowledge of blood sampling was not well, 62 (39.2%) was good, and 15 (15.2%) of students was excellent 135 (91%) students during the study program met with tube types and anticoagulants for blood sampling and 14 (9%) did not. In the end, 144 (97%) students considered that the preanalytical phase should become an integral part of the curriculum, medical laboratory diagnostics, and 5 (3%) students considered it not necessary. CONCLUSION: According to the conducted research, students have learned average theoretical knowledge of preanalytic, but less than half of them are not satisfied with the practical knowledge of blood sampling. The health professionals of the laboratory medical diagnostics play an important role in the preanalytical phase and the preanalytical should become a separate unit of the curriculum, the laboratory medical diagnostics study.
