autoimmune disease testing

Autoimmune disease testing involves analyzing blood samples to identify abnormal immune responses. Since autoimmune conditions occur when the immune system mistakenly attacks the body's own tissues, these tests look for specific autoantibodies—proteins meant to target foreign invaders but that instead target the body's cells. Common tests include measuring levels of autoantibodies like ANA (antinuclear antibodies), rheumatoid factor, and others specific to certain diseases. Results, combined with symptoms and clinical evaluation, help healthcare providers diagnose and distinguish autoimmune disorders, guiding appropriate treatment plans.
