Inter-laboratory test for tetracycline determination on teeth 2017: Report released and online

♦ 12 December 2017 ♦

The report of the inter-laboratory comparison on tetracycline and age determination in red fox teeth is now online (private part only). The fourth inter-laboratory session has revealed that 92% of participating laboratories presented 100% concordant results in the tetracycline detection test. Considering the age determination of the samples, 69% of the laboratories estimated concordant age class on the whole panel. Both TTC detection and age estimation have revealed the best results ever obtained in such inter-laboratory comparison! These results demonstrate a constant high level of performance of the laboratories in the detection of tetracycline and a high improvement in age determination. For the few remaining discordant results some points are discussed in the discussion section of the report.
