METHOD FOR EXANIMATION OF ELEMENT IN LIVING BODY

摘要

The purpose of the present invention is to measure the content of a mineral element in the body of a test subject by a hair test nutritionally and/or medically significantly. According to this method, the signal ratio (PXRF (S)) of a mineral element contained in the hair of a test subject to sulfur contained therein is measured by fluorescent X-ray spectroscopy, and then is multiplied by a conversion factor (F) to determine the content (MXRF) of the mineral element in the hair. This conversion factor (F) is calculated according to the formula F = M0.ICP/P0.XRF (S) wherein: P0.XRF (S) is a reference signal ratio of the mineral element contained in reference hair collected from a person exclusive of the test subject; and M0.ICP is a reference content of the mineral element therein as determined by inductivity coupled plasma mass spectroscopy.
