Which blood condition would typically be assessed in a complete blood count (CBC)?

A complete blood count (CBC) is a fundamental laboratory test that evaluates various components of the blood. One of the primary components assessed in a CBC is the white blood cell count. This measure provides critical information about the body's immune response and can indicate the presence of infection, inflammation, or other medical conditions.

The white blood cell count specifically gauges the number of leukocytes (white blood cells) in a blood sample, which plays a vital role in identifying health issues such as infections, blood disorders, and immune system problems. A normal white blood cell count is essential for maintaining the body's ability to fight off infections and respond to stressors.

The other options do not pertain to the CBC. Blood glucose levels are typically evaluated through a different set of tests focused on assessing metabolic function and diabetes screening. Total cholesterol levels are part of a lipid panel, which measures the fats in the blood and is used primarily to assess cardiovascular risk. Serum electrolytes are measured through specific tests that evaluate the balance of minerals and electrolytes in the body, important for various physiological functions but not included in a standard CBC.
