The Department of Haematology is divided into two sections Clinical Haematology and Laboratory Haematology. The department provides diagnostic and treatment services to patients with bleeding and clotting disorders, as well as anaemia, haematological malignancies and haemolytic disorders. In addition, a variety of services are provided to patients with blood disorders such as excessive or deficient clotting, pregnant mothers with blood disorders, patients taking Warfarin and patients who have problems with their bloods secondary to other medical issues. These services include: Consultant and Nurse led outpatient clinics (e.g. Warfarin Clinic), day services in the Dunmanway Unit and a walk-in service in the Comprehensive Coagulation Centre. Patients are usually referred from within hospital or by their GP.

The department also provides a large laboratory service to the CUH and GPs in both Cork and Kerry. The laboratory is a reference centre for a number of specialised tests.

The Department manages laboratories in University Hospitals Kerry, Mallow and Bantry as well as supporting laboratory service in South Infirmary Victoria Hospital and managing clinical blood transfusion throughout the region.

The department is actively involved in research and clinical trials. The Department of Haematology CUH/UCC continues to promote translational research in conjunction with the Blood Cancer Research Network of Ireland (BCNI). The BCNI is a Science Foundation Ireland and Irish Cancer Society funded project to advance the care of patients with malignancy. The Department continues to publish with its research partners in UCC in Cancer Research, in the School of Public Health and in the School of Pharmacy. The Department works closely with the National Cancer Registry to promote improved registration of patients with blood cancers.
