This article describes the recent activities of the European Communities Co
nfederation of Clinical Chemistry (EC4). Main goal of EC4 is harmonization
of clinical chemistry in the European Union and Europe. EC4's actions conne
cted to that are training and registration of professionals, and accreditat
ion of laboratories. The 35000 professionals practising clinical chemistry
in the EU have different backgrounds (medical, pharmaceutical, science-orie
nted, veterinary, or microbiological). Thus, for the harmonization of train
ing of clinical chemists, EC4 has published a European: Syllabus for Postgr
aduate Training, and instituted a European Union Register for Clinical Chem
ists. The Syllabus is an indication of the level of requirements in postgra
duate training. The EC4 initiative to implement the European Register for C
linical Chemists is based on the 8 years vocational training necessary to o
btain sufficient knowledge in clinical chemistry according to the European
Syllabus. A guide to the EC4 Register has been published; registration lead
s to the title European Clinical Chemist (EurClinChem). The accreditation o
f laboratories must be based on a total quality management system. EC4 has
described guidelines (essential criteria) which it judges appropriate for e
stablishing the quality of medical laboratory service; it does not wish to
fulfil the role of an accrediting body. Moreover, a working group has been
set up to seek to harmonize the work of national accrediting bodies. Theref
ore, it is logical that EC4 monitors the activities of the different standa
rdizing bodies that might influence the practice of clinical chemistry in t
he EU. Finally, some aspects concerning the future strategy of EC4 are brou
ght forward.
