Inclusion Criteria:
Tolerant AAV participants:
* Age 18 years or older
* Diagnosis of granulomatosis with polyangiitis (Wegener's, GPA) or microscopic polyangiitis (MPA) according to the definitions of the Chapel Hill Consensus Conference (CHCC)
* History of being myeloperoxidase (MPO)-ANCA positive during a disease flare
* In clinical remission with Birmingham Vasculitis Activity Score for Wegener's Granulomatosis (BVAS/WG) = 0 and off all immunosuppression for ≥ 2 years
* Negative MPO-ANCA and proteinase 3 (PR3)-ANCA by ELISA at screening
* For women of child-bearing potential, a negative urine or serum pregnancy test at the time of screening
* Ability to sign and understand informed consent
* Willingness to comply with study procedures.
Non-Tolerant AAV participants:
* Age 18 years or older
* Diagnosis of granulomatosis with polyangiitis (Wegener's), GPA or microscopic polyangiitis (MPA) according to the definitions of the CHCC
* History of being MPO-ANCA positive during a disease flare
* Within the past 5 years, must have had a disease exacerbation, defined as an increase in the BVAS/WG score and re-institution of immunosuppressive therapy after therapy had been reduced or completely discontinued
* In clinical remission with BVAS/WG = 0 and on minimal maintenance therapy for ≥3 months prior to the screening visit. Minimal maintenance therapy is defined as:

* For women of child-bearing potential, a negative urine or serum pregnancy test at the time of screening
* Ability to sign and understand informed consent
* Willingness to comply with study procedures.
Healthy Controls:
* Healthy participant age ≥18 years
* For women of child-bearing potential, a negative urine or serum pregnancy test at the time of screening
* Ability to sign and understand informed consent
* Willingness to comply with study procedures.
