These tests are done by Immunology and require 5-10 mL clotted blood with full clinical details. Other autoimmune tests not listed here may be done in other sections and have different sample requirements - if in doubt as to what sample to take, please contact the laboratory.

The interpretation of all autoantibody tests is highly dependent on the likelihood of disease in the patient. The results should always be interpreted with the clinical features of the patient and never in isolation. Autoantibodies may be present in healthy individuals and may also occur transiently with intercurrent illness or may be induced by drug therapy. Conversely, autoimmune disease may be present in the absence of detectable autoantibodies. Do not use these tests as ‘screens’ for autoimmune disease but rather decide the clinical diagnosis and the likelihood of autoimmune disease and use specific autoantibody tests as diagnostic aids.
