2022 ACR/EULAR Eosinophilic Granulomatosis with Polyangiitis Classification Criteria
2022 ACR/EULAR eosinophilic-granulomatosis-with-polyangiitis classification; a cumulative score ≥ 6 (higher than the GPA/MPA ≥ 5) classifies as EGPA, applied only after a small/medium-vessel-vasculitis diagnosis with mimics excluded.

Example
- Maximum blood eosinophil count ≥ 1 x10^9/L
- Yes
- Obstructive airway disease
- Yes
Result: 2022 ACR/EULAR 8/14 — ≥ 6: classify as eosinophilic granulomatosis with polyangiitis.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Threshold
- a cumulative score ≥ 6 (one higher than GPA/MPA) classifies as eosinophilic granulomatosis with polyangiitis (sensitivity 85%, specificity 99%).
What you enter
- Maximum blood eosinophil count ≥ 1 x10^9/L (+5)
- Obstructive airway disease (+3)
- Nasal polyps (+3)
- Extravascular eosinophilic-predominant inflammation (+2)
- Mononeuritis multiplex or motor neuropathy not due to radiculopathy (+1)
- Positive cANCA or anti-PR3 antibody (-3)
- Hematuria (-1)
How this is calculated
- Items
- 7 items summed, range -4 to +14: eosinophils ≥ 1 +5; +3 each for obstructive airway disease and nasal polyps; extravascular eosinophilic inflammation +2; mononeuritis +1; cANCA/PR3 -3; hematuria -1.
