People with blood diseases are looked after and treated by the department of haematology. Blood cancers (leukemia, lymphoma, multiple myeloma), disorders associated with low haemoglobin (various types of anemia, including thalassemia and sickle cell anemia), bleeding disorders (haemophilia and others), and other rare diseases such as hemoglobinopathies, primary immunodeficiency, and others are all treated in the department.

Our hospital's haematologists study the components of blood – red cells, white cells, and platelets – to aid in the diagnosis and monitoring of blood illnesses such as anemias, leukemias, lymphomas, and malaria; and to evaluate blood coagulation abnormalities such as haemophilia and thrombophilia.

The following are examples of anomalies in the blood count.
Low haemoglobin or red blood cells cause anemia.
Leucopenia is a condition in which the number of white blood cells in the body is abnormally low.
Thrombocytopenia is defined as a low platelet count.
Polycythemia is a condition in which there are too many red blood cells in the body.
Leucocytosis is a condition in which there are too many white blood cells in the body.
Thrombocytosis is a condition in which there are too many platelets in the blood.

Many of the clients who are referred to these clinics are concerned that they have cancer. While this may be true for some individuals, the vast majority of those sent to the general clinic do not have cancer. All patients visited in the clinic will meet with a consultant, and the majority will do so on their initial visit.

Additional tests are frequently required to aid in the diagnosis. Additional blood tests may be required, and some individuals may additionally require X-rays, scans, and/or a bone marrow test. If these tests are ordered, the results will be presented to the patient. Many patients can then be dismissed from the Haematology Department, but others will require more investigation and treatment in a clinic dedicated to the kind of sickness diagnosed.

Red marrow and yellow marrow are the two main forms of bone marrow tissue.
The bone marrow of the body can be affected by disease. Damage or sickness can cause a reduction in blood cell production. A bone marrow transplant may be necessary to restore the body's ability to manufacture enough healthy blood cells.
