Mosaic Diagnostics is currently in the process of R&D and the manufacture of calibrators and surrogate matrices for PCR based and IHC based diagnostics. They are targeted for inclusion both in our propriety platforms but also for application to several commercialised CE-IVD workflows. Our quality reference standards range will allow for intrinsic quantification of sample processing including multiplexing. QRS are designed to be utilised for validation, verification and quality assurance activities of developers and users of devices and associated diagnostics.
