SpectraCell is the industry's leading provider of Functional Intracellular Analysis™ (FIA™), patented tests for assessing the function of specific vitamins, minerals, antioxidants and other essential micronutrients within an individual's white blood cells (lymphocytes).  FIA™ is the industry's gold standard for evaluating nutritional status. It provides a complete picture of an individual's functional intracellular nutritional status by measuring nutrients in white blood cells that are more consistent than in red blood cells.  This detailed nutritional information enables Dr. Marschall to develop individual treatments for his patients.
