Linda M. Thienpont, Pharm., PhD, certified in clinical chemistry and in the use of radioisotopes for in vitro diagnostic tests, is a full Professor at the University of Ghent (Belgium), where she teaches “Instrumental Analytical Chemistry” and “Statistics and Quality Control”. Her main research interests focus on development/implementation of standardization/harmonization concepts and improvement of clinical laboratory measurements. In this area, she has published over 150 peer-reviewed papers. Mass spectrometric reference measurement procedures (for substrates/metabolites, 25OH-vitamin D, total and free steroid and thyroid hormones) developed by Dr. Thienpont are listed in the Database of the Joint Committee for Traceability in Laboratory Medicine (JCTLM) (see: http://www.bipm.org/). She offers reference laboratory and consultative services to all major globally operating IVD manufacturers, who then participate in projects which she chairs such as the IFCC Committee for Standardization of Thyroid Function Tests. Previous international standardization programs which involved her laboratory include the European Commission-BCR, ADA–EASD, CAP, CEQAL, etc. Currently her laboratory serves together with NIST as the reference laboratory for the Vitamin D Standardization Program (NIH–ODS). Prof. Thienpont is also the founding member and co-chair of the JCTLM, chair of the CLSI C45-A guideline, a member of the AACC Harmonization Oversight Group and on the Clinical Chemistry Editorial Board. She was recipient of the Siemens Healthcare Diagnostics oral Communication prize (2008) and the IFCC-Robert Schaffer Award for Outstanding Achievements in the Development of Standards for Use in Laboratory Medicine (2011).
