What term refers to the number of leukocytes in a cubic millimeter of blood that is considered normal?

The range of 4,500 to 11,000 leukocytes per cubic millimeter of blood is considered normal for adults. This value reflects the typical concentration of white blood cells in a healthy individual, which play a crucial role in the immune system by helping to fight off infections and diseases.

When assessing a person’s health, the white blood cell count is a vital indicator. If the count falls within this normal range, it suggests that the body is maintaining a balanced immune response, indicating good health. Counts below or above this range could indicate various medical conditions, such as infections, inflammatory diseases, or bone marrow issues, prompting further medical evaluation or intervention.

Other ranges mentioned in the options do not reflect the standard medical understanding of normal leukocyte counts and could mislead anyone trying to confirm their health status based solely on white blood cell counts.
