The current study aimed to investigate the importance of blood tests and immunological tests in laboratory medicine. Autoimmune disease tests measure the amount of certain antibodies in the blood. Your body makes antibodies to attack and destroy substances such as bacteria and viruses. But in autoimmune diseases, antibodies attack and destroy your body's own tissues. This can lead to diseases such as rheumatoid arthritis, scleroderma, and lupus. These health problems affect connective tissues, such as the skin, joints, blood vessels, and other tissues.
