Answer

A hemogram may reveal leukocytosis and a left shift, indicating infection. However, the absence of leukocytosis does not rule out diverticulitis, as 20%-40% of patients have a normal white blood cell count. This is particularly true in patients who are immunocompromised, who are elderly, and who have less severe disease. A hemoglobin level is important when the patient reports hematochezia.
