Laboratory - rise in acute-phase reactants - erythrocyte sedimentation rate - decrease in hemoglobin - leukocytosis - pANCAs Endoscopy (not in acute phase!) - sigmoidoscopy - colonoscopy Radiology - barium enema
Slide 8-

Diagnosis relies on the patient's history, clinical symptoms, negative stool examination for bacteria, C. difficile toxin, and ova and parasites; sigmoidoscopic appearance and histology of rectal or colonic biopsy specimens!
