Diagnosis of CSU
This module reviews the clinical features, diagnostic criteria, and burden of chronic spontaneous urticaria (CSU), with guidance on differentiating it from similar conditions, minimizing diagnostic delays, and identifying endotypes in treatment-resistant cases.
1.
APPLY evidence-based diagnostic guidelines, including appropriate use of laboratory tests and imaging, to optimize the diagnostic workup for patients with CSU
2.
INTEGRATE knowledge of CSU endotypes and validated and emerging biomarkers, including total serum IgE levels, to individualize treatment strategies and predict response to targeted therapies
