Eosinophilic Granulomatosis with Polyangiitis ANCA Probability

Estimate ANCA positivity probability in EGPA (Churg-Strauss) and stratify vasculitic vs eosinophilic phenotype based on clinical features and eosinophil count.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Estimate ANCA positivity probability in EGPA (Churg-Strauss) and stratify vasculitic vs eosinophilic phenotype based on clinical features and eosinophil count

Each component has a specific meaning:

  • Clinical features — The clinical features recorded for the scenario being assessed.
  • Eosinophil count — The eosinophil count recorded for the scenario being assessed.

Note: Interpret the egpa anca probability result against the thresholds and context described above.

How to Use

Enter the clinical features, eosinophil count for the scenario you are assessing. Estimate ANCA positivity probability in EGPA (Churg-Strauss) and stratify vasculitic vs eosinophilic phenotype based on clinical features and eosinophil count. Use the egpa anca probability result to inform your calculation.
