How can blood test help diagnose ulcerative colitis?

ANSWER

blood test can show if you have anemia, which is a symptom of ulcerative colitis. Anemia happens when you don’t have enough red blood cells to carry oxygen to your tissues. A blood test will also help identify or rule out other infections.

The blood test can also detect a rise in white blood cells, a low level of the protein albumin, and an elevated C-reactive protein level, all of which can signal inflammation in your body.
