SUITED FOR THE DEVELOPMENT OF DIAGNOSTIC ASSAYS DETECTING LOCALIZED AND SYSTEMIC AUTOIMMUNE DISORDERS. Autoimmune diseases are a broad range of related diseases in which a persons immune system produces an inappropriate response against its own cells, tissues and/or organs, resulting in inflammation and damage.
Autoimmune diseases are a broad range of related diseases in which a persons immune system produces an inappropriate response against its own cells, tissues and/or organs, resulting in inflammation and damage. Autoimmune products SUITED FOR THE DEVELOPMENT OF DIAGNOSTIC ASSAYS DETECTING LOCALIZED AND SYSTEMIC AUTOIMMUNE DISORDERS There are over 80 different autoimmune diseases, and these range from common to very rare diseases. Some autoimmune diseases affect mainly one part of the body (e.g. organ-specific such as multiple sclerosis which attacks the nervous system, autoimmune thyroid disease, and Crohn’s disease which is localized to the gastrointestinal tract) whilst others are systemic (such as systemic lupus erythematosus, rheumatoid arthritis and systemic vasculitis). Systemic autoimmune diseases can affect many body organs and tissues at the same time and they are broadly classified into rheumatological/connective tissue disease and vasculitis (inflammation of blood vessels). Autoimmune diseases collectively affect approximately 5%to 10%of the population of the developedworld. Common autoimmune diseases such as thyroiditis, rheumatoid arthritis and diabetes affect more than 1 in 100 people. In contrast, a rare autoimmune disease such as Goodpasture’s disease (a form of vasculitis) affects around 1 in amillion people. Autoimmune diseases disproportionately affect women at a rate of 2-9x greater than for men. Diagnostics
Autoimmune diseases are usually diagnosed using a combination of clinical history, blood tests (autoantibodies, inflammation, organ function) and other investigations such as x-rays. Specifically, autoantibodies act as biomarkers helping to diagnose disease subsets and monitor autoimmune diseases. Many autoantibodies have well-defined target antigens and can be detected with high analytical sensitivity for a particular disease.

Disease
Tests
Includes rheumatoid arthritis, systemic lupus erythematosus (SLE), scleroderma, and other systemic autoimmune diseases. Inflammation in the blood vessels which can lead to serious consequences such as aneurysms. Blood clotting disorders, such as Antiphospholipid Syndrome (APS) which is a hypercoagulable state caused by antiphospholipid antibodies. Localized disorders that attack the gastrointestinal track such as Celiac Disease, Crohn’s Disease, UlcerativeColitis or Inflammatory Bowel Disease (IBS). Thyroid diseases (e.g. Hashimoto’s and Graves’ diseases), diabetes, adrenal fatigue, osteoporosis, infertility, polycystic ovary syndrome, and several others. Hashimoto’s and Graves’ disease are the most common autoimmune diseases.
