HERTSMI-2
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.

| 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 | |||||
