UK Biobank is a major national health resource. It has recruited 500,000 people aged between 40-69 years in 2006-2010 from across the country. Participants have undergone measures, provided blood, urine and saliva samples for future analysis, detailed information about themselves and agreed to have their health followed. Over many years this will build into a powerful resource.
Preliminary applications cost £250, if awarded, full costs are calculated based on the variables you request.
