Bullz,Good Morning. When you had your colonoscopy did your GI Dr. do biopsies ? At present, there is no laboratory test that can specifically identify the disease, but routine blood tests may reveal anemia, high numbers of white blood cells, and indications of inflammation, such as a high Sed Rate and increased levels of C-reactive protein.
Crohn's is often suspected in patients with recurring abdominal pain and a family history of the disease, or chronic inflammation of the skin or joints. Colonoscopy is then typically used to confirm the diagnosis, although this can sometimes miss disease that is limited to the end of the small intestine. The definitive test for Crohn's ( although this is debated by many) involves a barium enema, followed by abdominal x-rays that reveal changes in the digestive tract indicative of the disease. Newer tests include CT scan and wireless capsule endoscopy, where a small camera is swallowed and sends images as it passes through the digestive tract.
As medicine is always changing, new tests and treatments become multiple so choosing the best one for you is a bit tricky. My husband was dx by biopsy and visualization of his small bowel during surgery. His Dr. dx him as an appy however, when the surgeon saw his small bowel he could see the many ulcers.
Every time he has a scope his GI Dr. does a biopsy - He has been scoped many times over the past 38 years.
I wish you well and hope you find the answers to all of your questions.
Kindly,
Kitt
