Abstract
A method for examining a biological fluid whereby quantitative examinations of various minerals and methionine, one of essential amino acids, contained in a biological fluid can be conducted simply, accurately, and at a low price is provided, wherein using an X-ray fluorescence analysis device, content ratios of minerals contained in a biological fluid of a subject which can be taken by the subject to sulfur originating in methionine contained therein are measured, contents of the sulfur and the minerals contained therein are calculated using the measured content ratios and calibration curves previously prepared by X-ray fluorescence analysis of standard solutions of the sulfur and the minerals, and a content of the methionine contained therein is calculated on the basis of the calculated content of the sulfur.
Claims7
A method for examining a biological fluid, comprising the steps of:
- measuring a content ratio of a mineral contained in a biological fluid of a subject which can be taken by the subject to sulfur originating in methionine contained in the biological fluid using an X-ray fluorescence analysis device;
- calculating contents of the sulfur and the mineral contained in the biological fluid using the measured content ratio and calibration curves previously prepared by X-ray fluorescence analysis of standard solutions of the sulfur and the mineral;
- and
- calculating a content of the methionine contained in the biological fluid on the basis of the calculated content of the sulfur.
