Information is presented to help medical technology schools abroad evaluate their credentials in comparison to U.S. requirements. After defining the subfields of medical technology, also called medical laboratory science, a summary is provided of the educational requirements, the professional titles, and the certification recognition of medical laboratorians in the United States by two credentialing agencies. The systems of medical laboratory science education in Belgium, Costa Rica, Sweden, and the United Kingdom are reviewed and compared to medical laboratory science education in the United States. Data are included on the rate of access to upper secondary education in these countries and on the science requirements for professional recognition of medical laboratory science or medical technologists. Case studies of two medical laboratory science students who came to Northeastern University from other countries (Germany and Iran) are presented. Appendices include the addresses of U.S. accrediting/credentialing agencies, as well as national professional associations for medical laboratory technologists in Belgium, Sweden, the United Kingdom, and the United States.
