Overview
Laboratory Findings
There are no specific diagnostic laboratory findings associated with allergic colitis. Routine laboratory studies should be correlated with a carefully taken history and a detailed physical examination.[1]
Stool microscopy
May shows presence of increased eosinophils which is suggestive of allergic colitis in the presence of typical clinical findings
Complete Blood Count with Differentials and Peripheral Blood Smear
- A low hemoglobin or hematocrit with microcytosis or marginal normocytosis may be seen and indicative of iron deficiency anemia from blood loss
- Peripheral blood eosinophilia may rarely be seen especially in FPIES
- Elevated white blood cells with a left shift may be seen in severe acute FPIES
Iron studies
- Low ferritin with a high TIBC is suggestive of chronic blood loss by inflammatory bowel disease.
- High ferritin may be suggestive of anemia of chronic inflammatory conditions
Complete Metabolic Panel
- May show hypoalbuminemia especially in children with chronic FPIES
- Metabolic acidosis may be seen with FPIES
