The Environmental Mold and Mycotoxin Assay (EMMA) by RealTime Laboratories is a specialized test designed to assess the presence of mold and mycotoxins within indoor environments. By analyzing dust samples collected from a living or working space, EMMA identifies 10 of the most toxic molds and 16 harmful mycotoxins they produce.
This test is useful for identifying environments affected by potentially hazardous mold exposure: mycotoxins can be detrimental to human health, causing a wide range of symptoms and conditions. [8., 13.]
The Environmental Mold and Mycotoxin Assay (EMMA) test by RealTime Laboratories is particularly useful for individuals and professionals concerned with indoor air quality and its impact on health. Here are some groups who should consider getting an EMMA test:
Individuals with Unexplained Health Symptoms: People experiencing chronic symptoms such as fatigue, headaches, respiratory issues, skin irritation, and cognitive impairments without a clear diagnosis, especially if they do not respond as expected to medical treatments, might benefit from the EMMA test. These symptoms can sometimes be attributed to mold and mycotoxin exposure. [13.]
Homeowners and Tenants: If you live in or are considering purchasing a home that has a history of water damage, visible mold growth, or a musty odor, the EMMA test can help assess the risk of mold and mycotoxin exposure in your living environment. [5.]
Real Estate Professionals: Before buying or selling property, especially those with known issues of dampness or water damage, conducting an EMMA test can provide valuable information about the presence of mold and mycotoxins, potentially affecting the property's value and livability.
Healthcare Professionals: Doctors and healthcare providers treating patients with chronic, unexplained illnesses that could be related to environmental exposures may recommend the EMMA test to rule out or confirm current mold and mycotoxin exposure as a contributing factor. [13.]
Environmental Health Specialists: Professionals tasked with assessing and improving indoor air quality in homes, schools, offices, or public buildings can use the EMMA test to identify specific mold and mycotoxin threats and guide remediation efforts. [5.]
Schools and Childcare Facilities: To ensure a safe environment for children, who are particularly vulnerable to the adverse health effects of mold and mycotoxins, these facilities may undergo testing, especially after incidents of water damage or when indoor air quality concerns arise. [5., 8.]
Occupational Health and Safety Officers: In workplaces with potential mold exposure risks, such as older buildings, industrial sites, or those affected by water leaks, the EMMA test can help in assessing the environment and implementing safety measures to protect employees.
The EMMA test is a tool for anyone concerned about the potential health impacts of mold and mycotoxin exposure in their environment. By identifying the presence of toxic molds and mycotoxins, individuals and professionals can take informed steps towards mitigation and remediation, thereby improving health and safety.
The Environmental Mold and Mycotoxin Assay (EMMA) test by RealTime Laboratories is designed to detect the presence of specific molds and mycotoxins in indoor environments. This test focuses on identifying 10 of the most toxic molds and 16 harmful mycotoxins produced by these molds, offering a detailed assessment of the potential health risks associated with mold-contaminated environments. Here's a brief overview of what the EMMA test screens for:
The EMMA test targets 10 toxic molds known for their adverse health effects. These molds are commonly found in water-damaged buildings and can cause a variety of health issues, ranging from respiratory problems to more severe conditions affecting the nervous system, immune system, and more. The specific molds tested are chosen based on their toxigenicity and prevalence in indoor environments; their toxigenicity is determined by the type and toxicity of the mycotoxins they produce. The EMMA tests for the following molds:
Aspergillus fumigatus
Aspergillus ochraceus
Aspergillus flavus
Aspergillus terreus
Aspergillus niger
Penicillium brevicompactum
Aspergillus versicolor
Candida auris
Chaetomium globosum
Fusarium solani
Stachybotrys chartarum
Penicillium chrysogenum
The test also identifies 16 mycotoxins, which are toxic substances produced by molds. These mycotoxins include:
Zearalenone: Known for its estrogenic effects and potential to cause reproductive issues. [11.]
Ochratoxin A: Associated with kidney damage and carcinogenic effects. [7., 10.]
Verrucarin J: Potentially involved in immune system suppression. [4.]
Isosatratoxin F: A potent mycotoxin with immune-altering and cytotoxic properties. [5., 6.]
Roridin H, A, L-2, E: Part of a group of mycotoxins known as trichothecenes, which inhibit protein synthesis and can cause a wide range of health effects. [4., 9.]
Aflatoxin B1, G1, G2, B2: Considered among the most carcinogenic substances, primarily affecting the liver. [2.]
Verrucarin A: Another trichothecene with toxic effects on cells and the immune system. [5.]
Gliotoxin: Suppresses the immune system and is commonly associated with exposure to Aspergillus species. [12.]
Satratoxin G, H: Highly toxic trichothecenes that can cause severe respiratory and immunological effects. [3., 9.]
These mycotoxins are significant because they can persist in the environment even after the molds that produced them are no longer present. Exposure can occur through inhalation, ingestion, or skin contact, leading to a range of health problems depending on the type and level of exposure.
For the Environmental Mold and Mycotoxin Assay (EMMA) test by RealTime Laboratories, the sample collection process is straightforward, requiring dust samples from your environment. Here's a simplified guide on how to collect your samples and prepare them for shipping:
Dust samples are needed for the EMMA test. These samples can be collected from various sources within your living or working space to test for mold and mycotoxins.
No special preparation is needed before collecting the samples.
Wear Latex Gloves: To avoid contaminating the samples, put on a pair of latex gloves before starting the collection process.
Number of Samples: You may collect 1-3 samples depending on the areas you wish to test. Ensure to record the number of samples on the Chain of Custody form.
Visible Mold: Use the provided swab or gauze to collect a sample of the mold. Place the collected sample into the provided biohazard bag.
Dust from Air Conditioner Filters: Gather 1-3 grams of dust (roughly the size of a cotton ball) and place it into the provided biohazard bag or a clean ziplock bag.
Dust from Vents: Dampen the provided cotton swab or gauze with tap water. Swipe it over the vent to collect 1-3 grams of dust, then place it into the provided biohazard bag or a clean ziplock bag.
Chain of Custody Form: Complete this form, noting the number of samples collected, and include it with your shipment.
The test kit is prepaid, so no additional payment is needed. Make sure to fill out the Chain of Custody form but skip the payment information section.
Prepare Package: Place the sample bag(s) and the completed test forms into the provided shipping envelope. Seal it securely.
Tracking: Note the tracking number on the return label for your records.
Drop Off: Take the package to the nearest FedEx location. Do not use a drop box for sample submission.
Your test results should be available 7-10 business days after the laboratory receives your samples. Please note that processing times may vary, and Rupa Health cannot guarantee a specific timeframe.
Following these steps ensures your samples are collected and submitted properly for accurate analysis by RealTime Laboratories.
