Use the below chart to understand the risk level of your environmental testing results. This tool allows you to compare your lab numbers to established safety thresholds and see what they mean for health risk and remediation urgency.

Quick Interpretation Guide

HERTSMI-2 → Measures 5 toxigenic mold species. Scores >15 are unsafe for CIRS patients (Dr. Shoemaker standard).

Endotoxin → Indicates bacterial fragments (from dampness or HVAC issues). High levels can worsen respiratory, neurological, and immune symptoms.

Actinobacteria → Soil-based bacteria common in water-damaged buildings. High dominance & prevalence suggest a contaminated indoor microbiome.

Beta Glucans → are structural components of the cell walls of most fungi, including molds. So, when lab tests detect elevated beta glucan levels in air, dust, or surfaces, it indicates fungal biomass is present — whether the mold is alive or dead.

How to Read Your Results

Desired – Considered safe for re-entry. Minimal concern for sensitized individuals.

Acceptable – May provoke mild symptoms in highly sensitive patients. Monitor closely.

Unacceptable – Unsafe for CIRS patients. Urgent remediation required before safe occupancy.

What Should You Do if Levels Are Elevated?

• Borderline and lower: Increase cleaning and monitoring. Retest in 3–6 months.

Elevated or Very High:

• Consult a CIRS-aware Indoor Environmental Professional (IEP)
• Identify & eliminate moisture sources
• Remove contaminated materials
• Perform deep cleaning & decontamination
• Retest before re-occupying
