Expert answer:
The low monocytes, a condition also known as monocytopenia, may be caused by, among several other reasons: Stress, therapy with immunosuppressants, acute leukemia, use of corticosteroids, aplastic anemia.
The reference value (normality) for monocytes is 200 to 1000 per cubic millimeter of blood, which corresponds to 2 to 10% of total leukocytes (4000 to 10000 / mm3). In case of monocytopenia, a physician should be consulted for evaluation and appropriate treatment if necessary.
