what is ermi?

The Environmental Relative Moldiness Index (ERMI) was developed by the U.S. Environmental Protection Agency, Office of Research and Development (ORD) as a research tool to investigate mold contamination in homes. The methodology is based on using mold-specific quantitative polymerase chain reaction (MSQPCR) to quantify 36 molds and calculate an index number for comparison with a database of reference homes. Very few labs provide this testing.

why ermi?

People who are suffering from chronic respiratory syndrome, allergies, asthma, respiratory infections, chronic obstructive disease, restrictive lung disease, chronic rhino sinusitis and other conditions are often not aware that their health issue could be caused by the home they live in. According to the EPA research, up to 50% of homes and workplaces in the US have past or current water damage. Approximately one in four people are genetically susceptible to develop respiratory illness due to exposure to the interior environment of a water damaged home. These water damaged homes are capable of triggering systemic inflammation in persons living in these homes. These homes can support the growth of toxin-producing fungi and a host of other contaminants such as; Mycotoxins, Gram-positive bacteria, Gram-negative bacteria, Cell fragments, Hyphal fragments, Beta Glucans, Endotoxins Actinomycetes, Microbial VOCs, Cell wall components, Mycoplasma, Chitinases, Lipopolysaccharides, Conid, Bioaerosols , Lip polysaccharide, Mycobacterium, Ultrafine particulates, Nano-sized particulates.

The Environmental Relative Moldiness Index (ERMI) developed by the EPA is used to determine if these contaminants are present in your home. A sample of house dust is taken. This dust sample is analyzed using the method of Mold Specific Quantitative Polymerase Chain Reaction (MSQPCR) to detect and quantify species of fungi found in the dust sample. These methods will give you a history of the home and reveal whether water damage has ever occurred.

ERMI Testing (dust test) Also includes other MSQPCR testing

Cost:

On the more expensive side for a single test.

Who Performs It?

It can be performed professionally, DIY, or hybrid: DIY under the guidance of an IEP.

How Does it Work?

Order from the laboratory's website or through your IEP, and then use the laboratory-provided package to collect dust on an electrostatic cloth according to instructions. Cloth is mailed to the laboratory. Dust is analyzed for mold DNA. Other dust collection methods are occasionally used, including vacuuming or HVAC filter cut-out.

Strengths

  • Shows 'history' of average exposure over time.
  • Prioritizes 36 mold species that may be of higher concern to health.
  • DNA-based: recognizes both 'live' and 'dead' mold spores, while some tests can capture only 'live' spores.

Weaknesses

  • By nature, the test is incomplete and includes only 36 mold species (there are thousands of species).
  • Results can be skewed by sampling (wiping) in incorrect locations such as directly on mold growth.
  • Interpretation based on the ERMI "score" is not recommended by ISEAI. Professional interpretation of the raw data is recommended. Concentrations of individual molds, including outdoor molds, need to be considered. It does not generally indicate sources of mold exposure; one has to do a separate investigation. (Performing multiple ERMI tests in multiple rooms or floor levels can provide some location information, but this may get expensive).

Is it the best test?

  • Each type of test is valuable under certain needs and circumstances. Each type of test can be invalid when it is performed incorrectly.
  • This is a non-profit resource created for general educational purposes. This does not provide individualized advice and should not replace the judgment of your own IEP and medical professional. Please read the disclaimer at the end. Last revised 4/23.
HERTSMI-2 Testing (dust test) Also includes other MSQPCR testing

Cost:

Mid-range; less expensive than ERMI.

Who Performs It?

It can be performed professionally, DIY, or hybrid: DIY under the guidance of an IEP.

How Does it Work?

Order from the laboratory's website or through your IEP, and then use the laboratory-provided package to collect dust on an electrostatic cloth according to instructions. Cloth is mailed to the laboratory. Dust is analyzed for mold DNA.

Strengths

  • Shows 'history' of average exposure over time.
  • Prioritizes five mold species that may be of higher concern to health.
  • DNA-based: recognizes both 'live' and 'dead' mold spores, while some tests can capture only 'live' spores.

Weaknesses

  • By nature, the test is incomplete and includes only five molds (there are thousands).
  • Results can be skewed by sampling (wiping) in incorrect locations such as directly on mold growth.
  • Major life decisions based on "score" alone are not recommended by ISEAI. Professional interpretation is recommended. Concentrations of individual molds, including outdoor molds, can have an impact that makes the 'score' incomplete.
  • It does not indicate sources of mold exposure; we have to do a separate investigation (performing multiple HERTSMI tests in multiple rooms or floors can provide some location information, but this gets expensive).
