Abstract: Disclosed are tests, correlations and “theranostic” interventions aimed at optimizing general health through quantification of cells with regenerative potential in circulation. Some embodiments include use of circulating endothelial progenitor cell (EPC) testing as a means of quantifying general health status in a patient. The combination of EPC testing together with a naturopathic intervention, wherein the selection and dosage of said naturopathic intervention is tailored based on said quantitative test is provided. In other embodiments, regenerative cells are selected from the group comprising of very small embryonic like cells (VSEL), CD34 cells with hematopoietic potential, and circulating mesenchymal stem cells (MSC). Naturopathic interventions include recommendations of lifestyle modification, dietary supplements, intravenous vitamins, detoxification, acupuncture, and guided imagery.
