FDA Guidance for the Industry

Technical Performance Assessment of Digital Pathology Whole Slide Imaging Devices

By Global Compliance Seminar (LinkedInTwitter)

FDA is issuing this guidance to provide industry and agency staff with recommendations regarding the technical performance assessment data that should be provided for regulatory evaluation of a digital whole slide imaging (WSI) system. This document does not cover the clinical submission data that may be necessary to support approval or clearance. This document provides our suggestions on how to best characterize the technical aspects that are relevant to WSI performance for their intended use and determine any possible limitations that might affect their safety and effectiveness.

Recent technological advances in digital microscopy, in particular the development of whole slide scanning systems, have accelerated the adoption of digital imaging in pathology, similar to the digital transformation that radiology departments have experienced over the last decade. The FDA regulates WSI systems manufacturers to ensure that the images produced for clinical intended uses are safe and effective for such purposes. Essential to the regulation of these systems is the understanding of the technical performance of the components in the imaging chain, from image acquisition to  image display and their effect on pathologist’s diagnostic performance and workflow. Prior to performing non-technical analytical studies (i.e., those using clinical samples) and clinical studies to evaluate a digital imaging system’s performance, the manufacturer should first determine the technical characteristics that are relevant to such performance for its intended use and determine any possible limitations that might affect its safety and effectiveness.

This draft guidance, when finalized, will provide recommendations that should be included in the assessment of technical characteristics of a WSI device.
