What is the normal percentage range of monocytes in a healthy individual?

  1. 10%

  2. 6%

  3. 12%

  4. 3%

The correct answer is: 6%

The normal percentage range of monocytes in a healthy individual typically falls between about 2% and 8% of the total white blood cell count. Therefore, a result of 6% aligns with this normal range, indicating that the individual’s immune response is functioning effectively. Monocytes are a type of white blood cell that play a critical role in the immune system, including the phagocytosis of pathogens and the presentation of antigens to T cells. Understanding this percentage is important for evaluating the body’s immune status and detecting potential health issues. A value significantly outside this range could indicate a variety of conditions, such as infections, inflammatory diseases, or hematological disorders.
