Autoimmune blood disorders are conditions in which the immune system mistakenly targets healthy components of the blood. Depending on the affected cells or proteins, these disorders can interfere with oxygen transport, immunity, or normal blood clotting. Common examples include autoimmune haemolytic anaemia, immune thrombocytopenia (ITP), and autoimmune neutropenia.

Symptoms vary according to the blood component involved. People may experience persistent tiredness, weakness, pale skin, breathlessness, frequent infections, easy bruising, nosebleeds, or prolonged bleeding. Some autoimmune disorders can also increase the risk of abnormal blood clots. In certain cases, symptoms develop gradually, while others may appear suddenly.

Diagnosis generally involves a detailed medical history, physical examination, complete blood count, blood smear, and specialised immune or antibody testing. Additional investigations may be required to identify underlying infections, autoimmune diseases, medications, or other contributing factors.

Treatment depends on the specific disorder, severity, and underlying cause. Corticosteroids and other immunosuppressive medicines may be used to reduce harmful immune activity. Intravenous immunoglobulin, targeted biological therapies, blood transfusions, or other treatments may be considered when appropriate.

Early diagnosis and regular monitoring can help control symptoms, prevent complications, and improve quality of life. Management should be individualised and guided by a qualified haematologist.
