Complete Blood Count - DETAILED ANSWER-The CBC is a serum diagnostic test that
measures red blood cells, white blood cells, hemoglobin, hematocrit, and platelets. The CBC
includes a differential of the white blood cells. A CBC is often included as part of routine health
screening or to obtain information related to specific conditions. In mental health, the CBC is
used to rule out medical conditions that may present with symptoms that can be attributed to
both medical and psychiatric diagnoses. For example, the CBC can help rule out anemia as a
cause for depressive symptoms and fatigue or rule out infection as a cause of acute mental
status changes. The CBC is also used to monitor certain treatment regimens. For example,
some medications, such as clozapine, require routine analysis of absolute neutrophil count and
platelet levels.
