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.
