Leica Biosystems is providing the following resources and references in an effort to support customers interested in validating digital pathology for remote use during the COVID-19 Emergency. It is the responsibility of clinical laboratories, hospitals and other healthcare facilities to consider performing a validation study as they deem necessary before the implementation of digital pathology for remote reviewing and reporting of digital pathology slides. These references may not meet all the requirements for validation. Therefore, it is the customer’s responsibility to validate their individual equipment set-up and clinical intended use, to meet institution’s needs
