This scoring system is application of the DNA testing shown on ERMI test results. The new roster is designed to help patients (previously sickened by water-damaged buildings) understand if a given building is safe for occupancy. The roster is based on the results of 738 ERMI consecutive test results with 592 that were over 2 and 146 under 2.

We selected five species of fungi from Group I of ERMI based on two criteria.
1. Representative of varied water saturations (60-80%; 80-90%; 90-100%).
a. Relative risk for enrichment is WDB compared to non-WDB is at least 10 The ratio of incidence in ERMI >2 divided by the Incidence in ERMI <2 must be >10.




We use a point system. Units are Spore E/mg.        
10 points are assigned for          
Aspergillus penicilloides >500        
Aspergillus versicolor >500        
Chaetomium globosum >125        
Stachybotrys chartarum >125        
Wallemia sebi >2500        
6 points are assigned for          
Aspergillus penicilloides 100-499        
Aspergillus versicolor 100-499        
Chaetomium globosum 25-124        
Stachybotrys chartarum 25-124        
Wallemia sebi 500-2499        
4 points are assigned for          
Aspergillus penicilloides 10-99        
Aspergillus versicolor 10-99        
Chaetomium globosum 5-24        
Stachybotrys chartarum 5-24        
Wallemia sebi 100-499        
Interpretation of HERTSMI-2 Score          
<11      Statistically safe for re-entry for those with CIRS        
11-15   Borderline; clean first and re-test before re-entry        
>15      Dangerous for those with CIRS. Do not enter.         
HERTSMI-2 is a building index. No one HERTSMI-2 can possibly show all areas of a given building.   
HERTSMI-2 does not replace careful observation of symptoms and lab results obtained following re-exposure
