Establishing DNA-based Standard For Mold Testing And Indoor Air Quality Analysis
04/24/07
The Chiodo Companies, Inc. announced today a strategic partnership with
Roche Diagnostics aimed at setting and advancing a DNA-based standard for mold detection. The
partnership encompasses a joint marketing effort and the co-development of new and customized solutions
targeted at both the commercial and end user markets.
Effective immediately, Clean Air Labs, The Chiodo Companies' R&D and analysis laboratory, will move
its real-time Polymerase Chain Reaction (PCR) analysis to the Roche Diagnostics platform. Clean Air
Inspections, the environmental consulting arm of The Chiodo Companies, Inc, will continue working with
its clients to transition from spore-trap sampling, to a sampling methodology better suited for DNA
analysis.
DNA-based mold detection using quantitative real-time PCR has been shown to be superior to the widely
used spore trap methodology. This DNA-PCR method, developed and patented by scientists at the United
States Environmental Protection Agency (US-EPA), provides a rapid, simple and standardized alternative
for mold analysis that can reduce uncertainties in interpretation of results. The recently licensed EPA assay
utilizes a panel of unique genetic markers from key species of molds associated with water intrusion, that
are of particular importance to building owners and occupants. Each DNA sample tested by Clean Air
Labs will be screened for these genetic markers to provide a more complete picture of mold contamination
present. Commercial availability of the Roche EMRI qPCR Mold Detection Kit helps provide an objective
and standardized result that will allow inspectors to provide highly informed recommendations to clients.
"We are acutely aware of the inferiority of spore-trap analysis and the direct benefits of DNA analysis
utilizing real-time PCR," said Ed Sobek, PhD, Chief Scientist of The Chiodo Companies. "With the recent
licensing by the EPA of Clean Air Lab to utilize real-time PCR analysis for DNA testing and our
partnership with Roche Diagnostics, The Chiodo Companies continues to be at the forefront of new
developments in the industry. This partnership will enable our two companies to drive the movement of
the entire industry to this platform by ensuring lower cost of analysis, better results and the ability to better
understand how molds impact human health."
"At Roche Diagnostics we are committed to leveraging our diagnostic technologies and expertise to bring
more accurate and efficient solutions to the field of environmental testing," said Oliver Strobel, Director of
New Business Development at Roche Diagnostics Applied Science. "The release of our EMRI Kit is an
exciting example of that commitment, and our strategic relationship with The Chiodo Companies is an
important step in our plans to bring future integrated workflow solutions to this market."
