In the medical field, haematology includes the treatment of blood disorders, including abnormal blood counts, types of anaemia, leukaemia, lymphoma, myeloma, bleeding disorders, blood clots, sickle-cell anaemia and thalassaemia. 

Haematology is a branch of internal medicine that deals with the physiology, pathology, aetiology, diagnosis, treatment, prognosis and prevention of blood-related disorders. 

We are Consultant Haematologists

Haematologists focus largely on lymphatic systems and bone marrow and may diagnose blood count irregularities. 

We treat organs that are fed by blood cells, including the lymph nodes, spleen, and lymphoid tissue.

We specialise in recognising and treating blood and bone marrow disorders and diseases, where correct prompt diagnosis is extremely important.

Depending on the symptoms you have,  you may need to have blood tests and/or other investigations such as a CT scan or bone marrow biopsy.
