What Is Driving Your Chemical Sensitivity?

Most people with MCS have never been tested for the four biological drivers most likely causing their reactions. This tool walks you through 7 questions and returns a personalized profile — specific tests, what to say to your doctor, and actions you can take right now, with or without a practitioner.

Most people with MCS have never been tested for the four things most likely driving it: mold illness (CIRS), mast cell problems (MCAS), autonomic dysfunction (dysautonomia), and a nervous system stuck in a state of overreaction.

Most people have more than one. This page asks you 7 questions and gives you back a personal profile — which drivers look likely for you, the exact tests to ask for by name, and what to say to a doctor who may not know this condition. You can use it whether or not you currently have a practitioner helping you.

What Is Actually Driving Your Chemical Sensitivity?

Most people with MCS have one or more of four biological drivers — CIRS, MCAS, inherited susceptibility, or central sensitization — and have never been tested. Answer 7 questions for your roadmap: specific tests, doctor scripts, and next steps.

CIRS / Biotoxin
MCAS / Histamine
Detox Gene Variants
Central Sensitization
Most people have more than one driver active simultaneously. This roadmap helps identify yours — so you know which tests to prioritize and which treatment pathways apply to your specific situation.
A note before you begin: This tool is an educational starting point, not a diagnosis. Before attributing your symptoms to MCS or related conditions, a thorough medical evaluation by a qualified physician should rule out other causes — thyroid disorders, autoimmune conditions, inflammatory diseases, and others that can produce similar symptoms. That evaluation comes first. This tool is designed to help you navigate after — or alongside — that process, particularly when standard medicine has not provided answers.
