Anti-neutrophil cytoplasmic antibodies (ANCA)

Anti-neutrophil cytoplasmic antibodies (ANCA) are a type of antibody produced by the immune system that mistakenly attacks certain proteins found in neutrophils, a type of white blood cell. These antibodies can contribute to inflammation and damage in various organs, leading to conditions like vasculitis, which involves inflammation of blood vessels. Testing for ANCA can help diagnose autoimmune diseases and guide treatment. ANCA-related diseases can affect the kidneys, lungs, and other organs, making early detection and management crucial for better health outcomes.
