A: SpectraCell’s FIA™ tests are more clinically useful than standard serum tests. Standard tests only measure static quantities of vitamins and minerals present in serum, primarily reflecting dietary intake. But, with our patented technology, we assess long-term intracellular requirements using each patient’s lymphocytes. Under a variety of nutrient depletion conditions, we measure the growth response of these cells to mitogenic stimulation. This determines functional intracellular deficiencies, which might not be detected by standard serum tests, and provides a powerful clinical assessment tool.
