The present invention relates to a diagnostic agent for diabetes, comprising a compound labelled with 13C at least at one specific position selected from the group consisting of the following (a) to (g):(a) galactose, fructose or xylose labelled with 13C at least atone specific position, or a starch composed of glucose units labelled with 13C at least at one specific position;(b) an amino acid labelled with 13C at least at one specific position;(c) lactic acid or citric acid 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;(f) glycerol labelled with 13C at least at one specific position; and(g) aminopyrin of which the dimethylamino group at position 4 is labelled with 13C, phenacetin of which the ethoxy group is labelled with 13C at position 1, or methacetin of which the methoxy group is labelled with 13C.According to the present invention, there is provided a diagnostic agent for diabetes which does not impose a heavy physical burden on a subject, can give accurate test results immediately and can be used safely without side effects. The diagnostic agent of the invention makes it possible to discriminate patients with diabetes from normal subjects even under circumstances where patients are easily missed.
