Patent ID: 7829295

Claim:
A method for judging stages between a pre-remission phase and a remission phase of ulcerative colitis, the method comprising: setting a base value of a main metabolite of prostaglandin, 7α-hydroxy-5,11-diketotetranor-prosta-1,16-dioic acid (PGE-MUM), concentration in urine obtained by measuring PGE-MUM comprised in the urine of patients diagnosed as being in the remission phase of ulcerative colitis under a therapeutic control with the administration of anti-inflammatory drugs; and judging that ulcerative colitis is in the pre-remission phase when the value of PGE-MUM concentration in urine of the patients is in a range exceeding the base value and being not more than 3 times the base value, and that ulcerative colitis is in the remission phase when the value of PGE-MUM concentration in urine of the patients is in a range of not more than the base value.
