IDPDL1 is an AstraZeneca  site providing references and educational material for healthcare professionals interested in PD-L1 testing.

Over recent years, there has been increased interest in the potential use of biomarkers in cancer.PD-L1 is one such biomarker. The aim of iD PD-L1 is to provide information for pathologists on PD-L1 expression testing, including: the pre-analytical stages, the practicalities of using, reading, interpreting and reporting PD-L1 assays, and training/quality control measures

Professor Patrick Pauwels discusses the role of PD-L1 testing for immunotherapy in a short video.
