Lawrence B. Afrin, Tania T. Dempsey and Gerhard J. Molderings (2023). This article discusses the role and limitations of antibody testing in MCAS patients.

It states that the monitoring of clinical symptoms and repeated testing over time should be used to avoid misdiagnosis caused by misleading results.
