Abstract:
1. A method of evaluating a physical condition of a test subject comprising the steps of: (a) extracting at least one hair from a subject; (b) performing X-ray fluorescence analysis on at least one point of said at least one hair; (c) measuring a spectral peak value (P) of calcium (Ca) and a background value (S) from said X-ray fluorescence analysis; (d) obtaining a [Ca] concentration value of a person expressed by the formula (1); (e) performing steps (a) through (d) on a plurality of healthy persons and/or persons with Ca supplementation to establish a homeostatic standard lower level of Ca concentration in hair (st) with closing of Ca ion channels of cells expressed by the formula (2), which is derived from Ca in serum protein by the principle that the content of an element in the hair must be equal to the inflow of that element into the cells of the hair root from serum; (f) performing steps (a) through (d) on a plurality of persons with Ca deficiency characterized by the tendency for people over 50 years old to have Ca deficiency to establish another homeostatic upper level of Ca concentration in hair (up) with opening of Ca ion channels of cells expressed by the formula (3), (g) performing steps (a) through (d) for a person whose health is being evaluated as said test subject to establish a Ca concentration value for the evaluated person expressed by the formula (1); (h) comparing said Ca concentration value of said person whose health is being evaluated with said lower level of the formula (2) and upper level of formula (3) to determine whether Ca channels of cells are closed or open for evaluating the health.
