Ditto what k07 said. If you’re testing your home, I would do the ERMI over the HERTSMI-2 if you can afford it. I think the ERMI was $290 and HERTSMI-2 was $150.
You can post your results and questions here. We’ll help you get the most understanding from the test. Shoemaker and mold docs tend to focus exclusively on the overall ERMI result and the HERTSMI-2 score (which you can calculate from the ERMI results). You can get a whole lot more understanding about
your mold situation from the ERMI than just the bottom line. Also, don’t pay anyone (doctor) to calculate the HERTSMI-2 for you. You can do it yourself.
