Description
What Your ERMI Kit Includes
- Sampling instructions: guidance for collecting and submitting an ERMI dust sample.
- Collection materials: a dust collector, gloves, and a sterile swab in a protective case. Use the collection device specified in your ERMI instructions.
- Chain of Custody form: complete and return this form with your sample, project details, and sampling locations.
- Laboratory analysis: molecular testing for the 36 fungal targets in the ERMI panel and calculation of the ERMI score.
Collecting Your Sample
Follow the current ERMI instructions for sampling locations, collection area, duration, and combining dust collections. Seal and label the collection device before returning it to the laboratory.
Collection methods affect results and their comparison with the original ERMI reference data. Contact the laboratory before replacing vacuum-dust collection with swab sampling or another method.
From Sample to Results
- Receipt notification: an email confirms when your project arrives at the laboratory.
- Standard turnaround: 3 business days. The day your sample arrives is day zero.
- Detailed report: individual fungal target results and the calculated ERMI score are delivered by email when analysis is complete.
- Report consultation: call 1-866-547-1727 to arrange a 15-minute consultation with a mold expert.
36 Fungal Assay Targets
Each list entry represents one assay target. Fungal names may include alternative or historical names, such as Eurotium and Aspergillus. Where multiple species are listed together, the assay reports the target group rather than distinguishing each species individually.

Understanding your results: EPA developed ERMI for research and does not recommend routine public use. Interpret the score and individual target concentrations alongside sampling conditions, moisture observations, and building history. ERMI does not measure mycotoxins, determine fungal viability, diagnose a medical condition, or establish whether a building is safe or unsafe.
