Most nutrient testing looks at what's circulating in your blood at a single moment. The CNA (Cellular Nutrient Assay) looks at your cells instead — how your own lymphocytes respond, in culture, to 55 individual micronutrients and 49 antioxidants and botanicals. The lab uses your blood drawn once, and your immune cells serve as their own baseline control, so each nutrient is tested against your own cellular response rather than a population average.

The assay has two parts:

CMA (Cellular Micronutrient Assay) - tests your cells' proliferation response to 55 individual vitamins, minerals, amino acids, and other nutrients, and reports each as sufficient, borderline, or insufficient for your cells' needs.

REDOX/APA (Antioxidant Protection Assay) - measures your overall resistance to oxidative stress (your Redox Score), then tests 49 individual antioxidants and botanicals to identify which ones meaningfully improve your cells' resistance to that stress.

Results feed directly into VitaminLab, which builds a personalized supplement formula from your specific results - only the nutrients your test flagged as insufficient or borderline, plus antioxidants your cells responded to protectively. No guessing, no generic multivitamin.
