Home page Left / Right-sided Cell Receptors Why are a majority of medical problems one-sided? When assessing Cellular Nutrition with Acu-Cell Analysis, only essential, biological elements that have their own cell receptors are measured.  They are neurologically arranged into left-sided and right-sided groups and are discussed in associated pairs, as they function as an inseparable, interdependent unit. Trace mineral symptoms of excess or deficiency are generally one-sided, depending on their ratios to other chemical members, and depending which group they are neurologically assigned to.  In the event of calcification, it is not a high calcium level that results in the formation of a stone or spur, but calcium being high in ratio to associated or interactive elements. For instance, phosphorus and zinc have both left-sided cell receptors, so if either level is low in ratio to calcium, calcification would only take place on the left side of the body, whereas the cell receptors of manganese or magnesium are right-sided, as a result, any calcification would develop on the right side of the body only. The same rules apply to most nutrition-related inflammatory or degenerative conditions, so successful, non-symptomatic treatments require the application of those same principles.  Since intracellular and serum levels of nutrients represent different physiological and pathological processes, abnormal levels seen in one medium are not necessarily reflected in the other, so they need to be interpreted differently.
