Method for detecting disease

A method for detecting at least one disease selected from the group consisting of visceral fat accumulation, hyperglycemia, dyslipidemia, hypertension and atherosclerosis or a disease two or more of which are combined or detecting onset risk of these diseases, which comprises

• (a) a step of measuring a ganglioside GM3 in a blood sample derived from a subject,
• wherein the ganglioside GM3 has a structure represented by the following formula (1):
• wherein R1 represents a glycan constituting the ganglioside GM3, and R2—C(═O)— represents a fatty acid residue having 16 or more and 24 or less carbon atoms which may have a double bond, and having an OH group as a substituent.

A detection kit, for detecting at least one disease selected from the group consisting of visceral fat accumulation, hyperglycemia, dyslipidemia, hypertension and atherosclerosis or a disease two or more of which are combined, or onset risk of these diseases, which contains a ganglioside GM3 as a standard substance,

• wherein the ganglioside GM3 has a structure represented by the following formula (1):
• wherein R1 represents a glycan constituting the ganglioside GM3, and R2—C(═O)— represents a fatty acid residue having 16 or more and 24 or less carbon atoms which may have a double bond, and having an OH group as a substituent.
