Online MCAS Clinical Diagnosis Test

Below you can take the free online HSA-MCAS (Hypersensitivity/Allergy-Mast Cell Activation Syndrome) Clinical Diagnosis Test which Dr. Aguirre-Chang digitalised with our team.

This test gives you a clinical diagnosis of the severity/level of Hypersensitivity/Allergy (HSA) and Mast Cell Activation Syndrome in Long Covid, Post Vaccine Syndrome, MECFS and other Chronic Illnesses and if further investigation is meaningful. 

*For technical reasons you will need to enter your email address once in all three parts of the test. After every finalised part/submission, please keep scrolling down. If you have issues scrolling down - use the scroll bar instead of touch scroll. (Always scroll to the bottom of every part to get to the submit button)

 Please allow 1-2 working days to receive your results by email. By submitting the online HSA-MCAS indication test above, you agree to us storing and processing the data submitted and using it for research. You agree to our privacy policy and to being signed up to our newsletter/blog. 

Dr. Gustavo Aguirre-Chang and Dr. Aurora Trujillo F. developed this test in November 2023.
