You could do a fecal calprotectin test, which will be high if the inflammation is worst in the rectum and sigmoid colon. Might not help your case if the inflammation is more distributed along the colon. But really, a colonoscopy is the golden standard for diagnosing a flare. Would a flexible sigmoidoscopy be any cheaper, as that's quicker and can be done without a sedation (although not necessarily comfortable if you're flaring...)?
