Assessment Tools

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:

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.
