Our unique biomedical database is the most comprehensive and most widely used of its kind, as we provide researchers worldwide with the data, tools and support to make discoveries which otherwise wouldn’t be possible.

Since 2006, UK Biobank’s half a million participants have been generously providing a vast amount of information about their health.

Researchers approved to work with the data can access it through our secure Research Analysis Platform. Participants’ identifying information is removed before researchers can access the data. 

Types of data

  • Imaging data
  • Biomarker data
  • Genetic data
  • Healthcare records

Data browser

Researchers can use our data browser Showcase to explore the data on our 500,000 participants in detail and discover how it might further their research. The browser contains background information on how these data were collected and includes notes about future collections.  

Approved researchers will need to use our Research Analysis Platform (UKB-RAP) to access the data. Our GitHub has some examples of how to access data on the UKB-RAP

Researchers can find more information and ask questions on the researcher Community site.
