Overview
Laboratory Findings
- Blood tests
A complete blood count may reveal anemia, which may be caused either by blood loss or [[Cyanocobalamin|vitamin BTemplate:Ssub]] deficiency. The latter may be seen with ileitis because vitamin BTemplate:Ssub is absorbed in the ileum.[1] Erythrocyte sedimentation rate, or ESR, and C-reactive protein measurements can also be useful to gauge the degree of inflammation.[2] It is also true in patient with ilectomy done in response to the complication. Another cause of anaemia is anaemia of chronic disease, characterized by its microcytic and hypochromic anaemia. There are reasons in anaemia, including medication in treatment of inflammatory bowel disease like azathioprine can lead to cytopenia and sulfasalazine can also result in folate malabsorption, etc. Testing for anti-Saccharomyces cerevisiae antibodies (ASCA) and anti-neutrophil cytoplasmic antibodies (ANCA) has been evaluated to identify inflammatory diseases of the intestine[3] and to differentiate Crohn's disease from ulcerative colitis.[4]
