METHOD FOR EXANIMATION OF ELEMENT IN LIVING BODY

摘要

The nutritionally and/or medically significant measured value on mineral elements contained in the body of a test subject can be detected by a hair test. The signal ratio PXRF(S) of said mineral element contained in the hair of said 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 element 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 P0XRF(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 element content of the mineral element therein as determined by inductivity coupled plasma mass spectroscopy.

1. A method for examination of element in living body comprising the steps of measuring a signal ratio PXRF(S) of a mineral element contained in a hair of a test subject to sulfur contained in said hair by a fluorescence X-ray analysis, and in order to calculate an element content MXRF of said mineral element from said signal ratio PXRF(S), multiplying said signal ratio PXRF(S) by a conversion factor F used in the calculation.
