Mold Testing Texas provides professional testing services across the Greater Austin metro with certified inspectors who specialize in ERMI (Environmental Relative Moldiness Index) mold testing. Developed by the U.S. Environmental Protection Agency (EPA) and the Department of Housing and Urban Development (HUD), the ERMI scoring system analyzes settled dust samples for 36 specific mold species using MSQPCR (Mold Specific Quantitative PCR) technology. Unlike traditional air sampling that captures a momentary snapshot, ERMI testing reveals the cumulative mold history of your home by examining mold DNA embedded in household dust.
The ERMI panel examines 26 Group 1 species (water-damage indicator molds) and 10 Group 2 species (common outdoor reference molds) to calculate a single numerical score that represents your home's relative moldiness compared to a national reference database.
