Less Is More: Diagnostic Testing for CSU

Author(s)Shawn Kwatra, MD, Naiem Issa, MD, PhD, Jennifer Hsiao, MD

Key Takeaways

Routine blood counts are crucial for initial diagnostic evaluation, providing baseline hematological data.
ESR and CRP tests are recommended to assess inflammatory activity, aiding in the diagnosis of inflammatory conditions.
IgG anti-TPO and total IgE tests are advised to evaluate autoimmune and allergic responses, respectively.

SHOW MORE

Panelists discuss how testing for chronic spontaneous urticaria (CSU) is recommended, with routine blood counts, including tests for erythrocyte sedimentation rate (ESR) and/or c-reactive protein (CRP), and specific antibody tests such as immunoglobulin G (IgG) anti- thyroid peroxidase (TPO) and total immunoglobulin E (IgE) being highlighted, according to guidelines.
