Vasculitis is a group of disorders characterized by inflammation of blood vessels, which can affect arteries, veins, and capillaries throughout the body. This condition can range from mild to severe and may involve single or multiple organ systems. Blood tests play a crucial role in diagnosing vasculitis and monitoring disease activity.
This test measures myeloperoxidase levels, an enzyme produced by neutrophils (a type of white blood cell). Elevated myeloperoxidase levels are commonly found in vasculitis due to the increased neutrophil activity and inflammation characteristic of this condition. This marker helps assess the degree of inflammatory response in blood vessels.
While vasculitis diagnosis often requires a combination of clinical evaluation, imaging, and sometimes tissue biopsy, blood tests are fundamental for detecting inflammatory markers, assessing organ function, and identifying specific autoantibodies. These tests help healthcare providers determine the type and severity of vasculitis and monitor treatment response.
Elevated myeloperoxidase levels may indicate active inflammation in blood vessels, but results must be interpreted alongside clinical symptoms and other diagnostic findings. Your healthcare provider will use these results as part of a comprehensive evaluation to determine the most appropriate treatment approach.
