The NIH Rapid Acceleration of Diagnostics Data Hub (RADx Data Hub) is a centralized data repository that provides access to analytic tools and de-identified COVID-19 data from the RADx Initiative. The RADx Data Hub better supports scientific efforts to understand COVID-19 and factors associated with disparities in morbidity and mortality in underserved and vulnerable populations, by allowing researchers to discover, access, and perform analyses of COVID-19 datasets in a cloud-enabled platform.

This tutorial provides in-depth, step-by-step instructions on how to use the features and functionality of the RADx Data Hub most effectively. If you still have questions after reading the tutorial, consult some of the other support documentation (e.g. the Frequently Asked Questions page or the Glossary) or reach out directly by using the “Contact Us” link in the main navigation bar or the footer.

The primary audience for this tutorial is external researchers. Internal NIH staff should consult the appropriate Standard Operating Procedures (SOPs) on the Resource Center page.

The RADx Data Hub contains several different features to help you get the most out of the system and better meet your research needs. These include:

• Common Page Navigation Tools: The RADx Data Hub features navigation tools (e.g. the navigation bar, the footer) that will lead you to different pages and features within the Hub.
• Home Page: The Home page is a one-stop shop for many of the key resources on the RADx Data Hub. From this page, you can quickly reach educational documents (e.g. the Frequently Asked Questions [FAQ], the User Tutorial), get information on news, funding opportunities, events, and study updates, search for studies, and view statistics on the information in the Hub.
• Study Explorer: The Study Explorer contains a number of discovery features (e.g. search, sorting, filtering) to help you quickly and easily find studies.
• Study Overview Pages: Each study in the RADx Data Hub has its own Study Overview page, which contains study metadata, variables, data files, and downloadable documents.
• Variables Catalog: This tabular resource lists all variables in each data file for each study. By viewing this resource, you can gain a deeper understanding of the key variables in a study to help you determine whether it aligns with your research goals before requesting access to the study.
• Support Resources: The system gives you multiple ways to submit a support request, so you can ask questions, report bugs, and request in-depth assistance from the Support team on complex questions. You can use the “Contact Us” link in the navigation bar or in the footer.
• User Registration: To access certain features, such as the Approved Data tab, you will need to first register with the RADx Data Hub. After you have registered, you can login using the “Login” button in the top-right of every page to access role-based features.
• Approved Data: After you have been approved for data, you can access the “My Approved Data” tab. From here, you can apply for a workbench instance, download data, or transfer it to your workbench instance.
• Public Data: The Public Data page has synthetic data files, which you can practice using our “Analytics Workbench” feature.
