The Health Categories dimension of the HRCS captures the area of health or disease being studied.
There are 21 separate categories which encompass all diseases, conditions and areas of health. Each of the Health Categories includes research into both disease and normal function.
e.g. studies of normal hepatic function and studies of liver cirrhosis will both be classified in the Oral and Gastrointestinal category.
Of the 21 categories, 19 refer to specific areas of health or disease. The Generic Health Relevance category has been included to capture research that is relevant to all diseases and conditions or to general health and well-being. The Disputed Aetiology and Other category is included to code research that does not fit within the Generic Health Relevance category or the 19 health specific categories.
For more advice, see our General Approach to Coding and Assigning Health Categories pages.
The Health Categories are based on the World Health Organisation (WHO) International Classification of Diseases (ICD) codes which cover all areas of disease and ill health.
Summary of health categories
Haematological diseases, anaemia, clotting (including thromboses and venous embolisms) and normal development and function of platelets and erythrocytes

- Research applicable to all diseases and conditions or to general health and well-being of individuals.
- Public health research, epidemiology and health services research that is not focused on specific conditions.
- Underpinning biological, psychosocial, economic or methodological studies that are not specific to individual diseases or conditions
Conditions of unknown or disputed aetiology (such as chronic fatigue syndrome/myalgic encephalomyelitis), or research that is not of Generic Health Relevance and not applicable to the top 19 specific health categories with specific pathological / physiological determinants.
