Mast Cell Activation Syndrome (MCAS) Simple Survey

This is a survey on Mast Cell Activation Syndrome Symptoms. The higher your score, the more likely you are to have Mast Cell Activation Syndrome. If you have a score over 50, investigate whether you might have Mast Cell Activation Syndrome.

The survey was developed by Beth O'Hara for their Master’s Thesis and Doctoral Dissertation. This is based on the work of top experts in the field and Dr. O'Hara's own clinical observations of thousands of people with Mast Cell Activation Syndrome (Afrin L. B., 2016) (Afrin L. B., 2013) (Akin, Valent, & Metcalfe, 2010) (Theoharis C.Theoharides, et. al., 2012). The interactive web app was developed by Joel Parker Henderson.
