Eloísa Urrechaga started her career in Clinical Chemistry in 1984 as a trainee in Hospital General de Asturias; she became head of Laboratory in a Community Hospital, Hospital de Jarrio in 1990. She is an expert of the Spanish Science and Innovation Ministry, in the Agency for Assessment of new technologies and the Health Research Council for the validation of research projects of the Czech Republic and Argentina. Member of the WHO Guideline Development Group – Ferritin International Micronutrient Malnutrition Prevention and Control, World Health Organization; member of European Network for Rare and Congenital Anaemias, member of International Society for Laboratory Hematology; collaborates with International Council for Standarization in Hematology; member of Analytical Hematology and Trace Elements Commissions of the Spanish Society of Medical Laboratory, She is particularly involved in the development of new hematological parameters applied to the study of anemia and erythropoiesis, early detection of infections and sepsis, as well as Glycohemoglobin.
