Although there is currently no official diagnosis for MCS/TILT/DELTA, several validated questionnaire instruments are available for assessing various aspects of environmental sensitivities or intolerance.
The Quick Environmental Exposure and Sensitivity Inventory (QEESI) is a widely used screening instrument for multiple chemical intolerance. Coupled with a comprehensive exposure history, it is useful in diagnosing MCS/TILT/DELTA. Developed by Dr. Claudia Miller and her colleagues, QEESI has been used by researchers and clinicians to document symptoms and intolerances in exposed individuals and groups in whom MCS/TILT/DELTA is suspected. Individuals find the QEESI helpful for self-assessment and screening.
Other available assessment tools include:
- Chemical Odor Intolerance Index (COII): a rating system for five substances (pesticide, patin, perfume, car exhaust and new carpeting) on a 5-point scale, regarding frequency of odor-related sickness
- University of Toronto Health Survey (UTHS): asks about information on general health status, relevant demographic characteristics, and explores the linkage of 171 symptoms to environmental exposures
- Chemical Sensitivity Scale (CSS): quantifies the degree of negative reactions and behavioral disruptions caused by odorous environmental substances
- Chemical Odor Sensitivity Scale (COSS): an 11-item screening scale for assessing strong responses to the odor of common environmental chemicals
- Idiopathic Environmental Intolerance Symptom Inventory: assesses the prevalence and attribution of 27 most commonly reported symptoms in five categories, with regard to environmental exposures and sources
- Environmental Hypersensitivity Symptom Inventory: covers a broader range of commonly reported symptoms, including non-specific building-related symptoms, sound intolerance and intolerance to electromagnetic fields
- Environmental Symptom-Attribution Scale (ESAS): quantifies the degree of health symptoms attributed to specific environmental exposures and sources using a 7-point category scale

You could fill out QEESI online and self-evaluate your environmental exposures and reactions related to MCS/TILT. By filling out this survey you will have the option to allow us to show your test result on a map, aggregated at the city level. No personally identifiable information will be collected in this survey.
