Ulcerative colitis (UC) is one of the two types of inflammatory bowel disease (IBD), with the other type being Crohn's disease. [1] It is a long-term condition that results in inflammation and ulcers of the colon and rectum. [1] [7] The primary symptoms of active disease are abdominal pain and diarrhea mixed with blood (hematochezia). [1]
Faecal calprotectin has been used to detect intestinal inflammation (colitis or enteritis) and can serve as a biomarker for inflammatory bowel diseases. [10] [12] Blood-based calprotectin (in serum and plasma) is used in diagnostics of multiple inflammatory diseases, including autoimmune diseases, like arthritis, and severe infections including ...
Crohn's disease and ulcerative colitis are the principal types of inflammatory bowel disease. Inflammatory processes result in an influx of neutrophils into the bowel lumen. [8] Since calprotectin comprises as much as 60% of the soluble protein content of the cytosol of neutrophils, it can serve as a marker for the level of intestinal ...
ASCAs and perinuclear antineutrophil cytoplasmic antibodies (pANCAs) are the two most useful and often discriminating biomarkers for colitis. [2] ASCA tends to recognize Crohn's disease more frequently, whereas pANCA tend to recognize ulcerative colitis. [3] ASCA antibodies react to a yeast protein with mannans, [4] a 200-kDa glycoprotein. [5]
The antimicrobial antibody ASCA is a well-known blood test marker used in the diagnosis of Crohn's disease. Approximately 60–70% of individuals with Crohn's disease test positive for ASCA, while only 10–15% of those with ulcerative colitis and less than 5% of patients with other types of colitis have positive results.

Mirikizumab, a drug currently approved by the Food and Drug Administration (FDA) for the treatment of ulcerative colitis, also sends Crohn's disease into clinical remission, new findings suggest.
No disease specific markers are currently known in the blood that would enable the reliable separation of patients with Crohn's disease and ulcerative colitis. [63] Physicians tell the difference between Crohn's disease and UC by the location and nature of the inflammatory changes.
