The Nutrition Evaluation Laboratory is a centralized laboratory with a comprehensive analytical program in clinical chemistry and biochemistry. Providing scientists with a full array of analytical services to help them achieve their diverse research goals and objectives, the NEL is committed to creativity, flexibility and technical expertise. Focused on quality, accuracy, precision, resourcefulness and customer satisfaction, the NEL offers scientific investigators a comprehensive biochemical test menu, specimen handling services and analytical study design assistance.
The Nutrition Evaluation Lab occupies 5,000-square feet and comprised of three units, Clinical Core Unit, Specialized Chemistry Unit and Specimen Processing Unit. Licensed by the federal government (Clinical Laboratory Improvement Amendments (CLIA) Certificate of Compliance from the CDC) and the Commonwealth of Massachusetts, (Div. Health Care Quality, Dept. Public Health), the NEL’s Clinical Core Unit provides results for hematology, blood chemistry, and urinalysis procedures. The NEL’s Specialized Chemistry Unit provides tailored analytical services for measurement of water-soluble vitamins, fat-soluble vitamins, lipids, proteins, amino acids, retinoids, carotenoids, antioxidants, carbohydrates, hormones, enzymes, cytokines, hematological parameters, and macro and micro mineral from human body tissues, animal tissues and food. The NEL’s Specimen Processing Unit receives, processes, stores, and tracks biochemical specimens. The NEL’s Information Management System provides infinite storage and archiving of specimen identification numbers and includes online quality control checking, workload reporting, and direct transfer of test results from instruments to research data base. We also provide expert assistance with protocol and analytical development.

The NEL adheres to a strict Quality Assurance Program. Each analytical procedure has Standard Operation of Procedure (SOP) for certification, linearity determination, proficiency testing and calibration. The laboratory uses the National Institute of Standard and Technology (NIST) reference and commercial materials for verification. The NEL participates in the College of American Pathologists (CAP) Inter-laboratory Comparison & Survey Program and the American Proficiency Institute (API) Testing Program for all licensed procedures. Other Inter-laboratory Round Robin and Quality Assurance Programs include NIST Micronutrients Measurement Quality Assurance Program, Northwest Lipid Research Center Proficiency &Quality Assurance Program, State of New York Department of Health Proficiency Testing Program, DEQAS Vitamin D External Quality Assessment Scheme and the NIST/NIH Vitamin D Metabolites Quality Assurance Program (VitDQAP). The laboratory uses David Rhodes Associates, Inc., EP Evaluator Program for statistical evaluation.
The NEL houses sophisticated equipment and a computer management system that allows efficient and effective support of the scientific and research requirements for our diverse customer population. With a comprehensive analytical program, our goals are to provide a high level of analytical precision, quality, and accuracy, with timely results, to every client, for every sample tested.
