Diagnostic agent for liver function

摘要

The present invention relates to a diagnostic agent for liver function, comprising a compound labelled with 13C at least at one specific position selected from the group consisting of the following (a) to (f): (a) galactose, glucose or xylose labelled with 13C at least at one specific position or a starch composed of glucose units labelled with 13C at least at one specific position; (b) a polar amino acid, heterocyclic amino acid, isoleucine or valine labelled with 13C at least at one specific position; (c) a carboxylic acid constituting the glycolytic pathway or the citric acid cycle, labelled with 13C at least at one specific position; (d) a fatty acid labelled with 13C at least at one specific position; (e) a glyceride labelled with 13C at least at one specific position; and (f) glycerol labelled with 13C at least at one specific position. According to the present invention, a diagnostic agent for liver function which imposes less physical burden on a subject, can give accurate test result immediately, and can be used safely without side effects is provided. The diagnostic agent of the invention is useful for evaluating the liver function of a subject at the time when the test is carried out.
