Summit Laboratory, LLC
Founded in 1999, Summit Laboratory brings the “Fusion of Science and Service” to the Great Lakes region. At Summit, we continually strive for excellence through our exacting standards in scientific analysis and quality, as well as our dedication to personalized attention and competitive prices.
Summit Laboratory is the first organization in the U.S. to receive accreditation for Environmental Swabbing from the A2LA. This is in addition to two other accreditations recently earned for Listeria spp. Testing and Salmonella spp. testing from Solus. Read the full story.
As an A2LA certified ISO 17025 accredited* laboratory, Summit is proven to have a world-class quality management system. Partnering with us means you’ll always receive data and documentation considered traceable and more defendable.
And because the ISO 17025 accreditation requires continual improvement through regular internal audits and adherence to the latest scientific and technological advances, you can rest assured that your samples are always at the right certified laboratory.

We Strive for Excellence Every Day
Efficient, affordable, quality analysis is only the beginning of the services Summit Laboratory provides. We pride ourselves on the relationships we establish and grow with our customers. We begin by working with you to identify your testing requirements and follow up with an explanation of the results of our analysis. We put the needs of our customers first and are committed to your complete satisfaction.
Our Scientists
We are a team that is truly passionate about what we do. Each of our scientists holds a degree in their area of expertise and brings years of experience and continuing education into each analysis. While that’s not guaranteed with all testing laboratories, we think it should be. Because at Summit, we understand a crucial part of quality analysis is accurate interpretation of the data. We provide these services with state of the art equipment that allows expedited results at prices competitive with industry standards.
Summit Laboratory specializes in servicing the following areas:
- Food Safety
- Facility and Equipment Environmental Monitoring and Training
- Water Testing
- Mold Testing
- Pharmaceutical Testing
- Third-party Product Testing and Claims Verification
QUALITY ASSURANCE PRACTICES
Summit Laboratory’s philosophy puts customers first. This means we must adhere to strict laboratory testing techniques and protocols that ensure correct and reliable data. To put it less scientifically, at Summit, we pay the utmost attention to quality control methods that enable us to not only obtain our certified laboratory status, but to stay abreast of changing regulations and methods of data collection as well.
QUALITY LABORATORY PRACTICES:
- Usage of only AOAC, FDA & USDA standard certified methods
- All samples are analyzed by professional biologists
- Certified quantitative and qualitative standards are routinely tested with samples
- Disposable pipette and plating equipment is used to help eliminate cross contamination
