- Blood cell counts: Complete blood count and white blood cell counts are used to diagnose IBD. In addition, the detection of C-reactive protein in blood and the evaluation of the erythrocyte sedimentation rate can help to determine the rates of inflammation and infection in the patient.
- Vitamin levels: Vitamin B12 levels and folate levels could indicate gastrointestinal malabsorption and bowel disease.
- Stool tests and cultures: Fecal calciprotein is used as a non-invasive marker of intestinal inflammation in patients with IBD. Stool samples need to be cultured to check for bacterial and protozoal infections.
- Serologic: Serologic testing is used to measure antibodies in the blood serum for inflammatory bowel diseases.
- Imaging techniques: Radiographic, CT, and MRI scans can all be used to diagnose IBD — especially to determine if a patient has ulcerative colitis or Crohn's disease.
- Invasive techniques: Biopsies and the study of tissue specimens may be used for severe cases of IBD.
