We are delighted to announce that the VitDAL has been awarded DEQAS accreditation this week. This demonstrates that the lab offers a 25(OH)D assay which has a high degree of accuracy and performs within the Vitamin D External Quality Assessment Scheme (DEQAS) performance targets. The DEQAS send VitDAL samples every 3 months in which we measure 25(OH)D concentrations blindly before submitting the results to the scheme. At the end of each annual cycle only labs which have performed within tightly controlled targets are awarded accreditation.  The photo shows the team proudly exhibiting their certificate of proficiency from the DEQAS Advisory Panel (L-R Dr Natalie Homer, Mass Spectrometry Core Manager; Dr Emma Hurst, VitDAL postdoctoral scientist; Dr Scott Denham, Deputy Director of Mass Spectrometry facility and Professor Richard Mellanby).
