This comprehensive guide for the diagnosis and management of MCAS in Primary Care is designed to help GPs to recognise and treat MCAS with confidence. We hope that this guide will serve as a useful, practical tool to help you to support MCAS patients and improve their quality of life. The 1-page Recognising and Managing MCAS Overview on P4 is a useful place to start if you are looking for a quick summary, and a full-page downloadable version of the flowchart can also be found on our website here https://www.mastcellaction.org/articles/recognising-and-managing-mcas-in-primary-care-overview-flow-chart
