Allergen Sampling Using The Epa Maria Method

When there is an undiagnosed health issue, it is highly recommended that comprehensive indoor allergen testing been conducted because this is used to detect and quantify the presence of cat, dog, cockroach, and dust mite allergens.

This is done to detect and quantify the presence of the two major dust mite (Dermatophagoides pteronyssinus and Dermatophagoides farinae) allergens, Der p1 and Der f1. Sensitive individuals have allergic responses to this protein which is found in high concentration in the mite’s feces.

This allergen analysis is performed at the laboratory by the MARIA method to identify these most common indoor allergens by DNA sequencing. 

Dust Characterization sampling can be done because that incorporates physical testing with Polarized Light Microscopy (PLM), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and X-Ray Diffraction (XRD) to identify nearly all unknown particles in dust from cotton fibers, dander and dust mites to unusual materials such as carbon black, metal oxides and minerals.

This analysis is best performed in conjunction with Indoor Air Quality Sampling, Air-O-Cell cassettes or other media to identify any fungal allergens.  This method is the perfect procedure for initial site surveys where Indoor Air Quality is in question, especially when someone inside the property is having issues.

Allergen Testing is for people who want to test for potential allergens in their homes or businesses.
