Overview
Diverticulitis diagnosis starts by taking history precisely and performing the physical examination. Lab tests are important in excluding other causes of abdominal pain and any other gastrointestinal disease. These lab tests include CBC, CRP, urinalysis and liver function tests. Imaging procedures are important measures in diagnosing diverticulitis including the CT scan and colonoscopy.[1][2]
Laboratory Findings
Diverticulitis initial diagnostic measure is taking a proper history ,doing a physical exam and performing lab tests. The lab tests are needed in the beginning in order to exclude other gastrointestinal diseases and to confirm diverticulitis. These lab tests include the following:
- CRP
- CBC: It may show leukocytosis, but if there is no leukocytosis that does not exclude diverticulitis as most of the patient have normal blood count.
- Urinalysis: It is performed especially in cases complicated by fistula. It may show the following findings:[3]
- Pyuria: in the case of urinary tract infection.
- Hematuria: in the case of nephrolithiasis takes place.
- Liver function tests: Amylase and lipase tests are required to exclude other diseases causing abdominal pain.
