1. A method for the treatment of an immune-mediated gastrointestinal disorder or a non-IBD autoimmune disease, said method
comprising:
(a) administering azathioprine or 6-mercaptopurine to a subject having an immune-mediated gastrointestinal disorder or a non-IBD
autoimmune disease;
(b) determining a level of 6-thioguanine present in said subject from red blood cells;
(c) indicating that said determined level of 6-thioguanine is associated with a higher likelihood of response when said determined
level of 6-thioguanine is between about 230 pmol per 8×108 red blood cells and about 450 pmol per 8×108 red blood cells; and
(d) considering said determined level of 6-thioguanine in the treatment of said subject.
