Enzymun-Test TG: results from external evaluation

Abstract:
A new non isotopic assay for determination of thyroglobulin has been developed by Boehringer Mannheim. This assay uses a new international reference material for calibration, that is thought to replace the current manufacturer specific standardization. Several aspects of the technical performance of this assay have been evaluated in a multicenter evaluation, including precision profile, lower detection limit, recovery testing and method comparison. Additionally reference ranges were established. The presented assay fulfils clinical and analytical needs and offers for the first time a calibration according to a new international certified reference material.
