Overview
Laboratory findings consistent with the diagnosis of bowel obstruction include hyponatremia and hypokalemia, leukocytosis, metabolic alkalosis and elevated serum lactate.
Laboratory Findings
- Laboratory findings that may be carried out in order to diagnosis bowel obstruction include:[1][2][3]
- Complete blood count
- To identify anemia, which may indicate a specific etiology such as Crohn's disease, Meckel's diverticulum or malignancy
- To identify leukocytosis
- Blood urea nitrogen
- Creatinine
- Eletrolytes
- The presence of hyponatremia and hypokalemia is often noted in cases of bowel obstruction
- Arterial blood gases
- Although not routine, is useful to assess systemic signs such as hypotension and also for cases of metabolic alkalosis
- Serum lactate
- Elevated serum lactate may suggest bowel ischemia
- Complete blood count
