What Are Antineutrophil Cytoplasmic Antibodies (ANCA)?
ANCA are abnormal antibodies found in the blood in most people with Wegener’s granulomatosis, a disease that affects the upper respiratory tract, lungs, and kidneys. They are uncommon in other diseases, which makes them useful in diagnosing this particular disease. ANCA levels are sometimes used to follow the course of Wegener’s granulomatosis.
