Abstract
Objectives: A recent challenge for clinical laboratories is the lack of clear guidelines for handling significant modifications of CE-marked assays. The modifications may involve, for example, extending measurement intervals, changing dilution procedures or using non-validated sample materials. The challenge arises due to the amended Regulation (EU) 2017/746 on in vitro diagnostic medical devices (IVDR), which is now poised for implementation, despite the extended transition periods. The IVDR application imposes challenges not only for diagnostic companies but also for clinical laboratories when using laboratory developed tests (LDTs), often referred to as in-house assays. In this context, a coherent and meticulously structured LDT documentation is highly beneficial. While laboratories are obliged to meet the IVDR requirements, the absence of a streamlined framework or guideline hampers the ability to gain a comprehensive overview on the requirements and possible options for their fulfilment.
Methods: To address this issue, we introduce a web based digital tool powered by an R Shiny web application. This tool facilitates a seamless implementation of IVDR requirements for LDTs across diverse laboratory environments in terms of their transparency and validity. Our approach focuses on adequate handling of significant modifications of CE-marked in vitro diagnostic medical devices (IVD).
Results: IVDRCheckR is an open-source tool that is easily accessible and free from system dependencies. The tool promotes a seamless process and a guide to enhance transparency, reliability, and validity of laboratory examination results based on LDTs. Additionally, the tool further provides modules for evaluating quality control data and quantitative method comparison data.
Conclusions: Our Shiny web application-based platform is a digitised, user-friendly tool that simplifies the documentation for LDTs according to IVDR requirements with special emphasis on solutions for handling modifications to CE-marked assays.
