Accelerated development of science and scientific inventions reflects also on the increasing number of diagnostic methods and procedures in laboratory diagnostics. Complexity of improving techniques demands continuing professional training. Therefore, a need has emerged for upgrading of the existing undergraduate education system in the field of medical laboratory diagnostics in Croatia. According to the Bologna Process, two Croatian universities, in Rijeka and Osijek, have launched graduate studies of Medical Laboratory Diagnostics (MLD). The aim of this paper is to show the possibilities for the improvement of the current MLD studies in Croatia by analysis of the university programmes in the United Kingdom and Ireland that within the Biomedical Studies offer studies in the MLD field. Although in the UK and Ireland there are no educational programmes in the MLD field identical to those in Croatia, in this paper the nearest equivalents are used for comparison. University education system in the UK and Ireland includes undergraduate, graduate and postgraduate levels. Students are offered different possibilities to choose desired degree level (BSc, BSc Hons, MSci, MSc, MRes), study programme (Blood Sciences, Cellular Sciences, Infection Sciences, etc.) and advancement in research or scientific career (PhD). The openness of the universities to the labour market provides a wide range of possible employments. For the purpose of this paper a detailed research of has been conducted of the study programmes at the following universities: Aberdeen, Brighton and Middlesex London in the UK, as well as Trinity College Dublin and Dublin Institute of Technology in Ireland. The comparative analysis method has been used in the research. The universities in the UK and Ireland are among highest ranked on the world scales of university education. Their models of the high education organization could serve as valuable “good practice” examples for the improvement of the organization of the current study programmes at the graduate studies of MLD in Croatia.
