If you have been treated with ANCA vasculitis and you are now in remission, you may be able to participate in a study to test if a specific blood test can help your doctor decide if you need maintenance therapy.

We are looking for patients with kidney disease and healthy controls (no kidney disease) to provide blood samples, fill out surveys, and provide health related information to help investigators learn more about how to better diagnose and treat kidney disease. The information you provide will go into a "library" of data for doctors and researchers across the world to use for research projects. If you are a kidney patient, we are able to use your information to find out if you are eligible for treatment studies/other studies in the future.
