What causes an elevated percentage of monocytes?
During a physical examination, the doctor told me that my monocyte percentage is elevated. I would like to ask the doctor, what are the causes of an elevated monocyte percentage?

An elevated percentage of monocytes typically means that the proportion of monocytes in the blood exceeds the normal range. The following are common causes that may lead to an increased monocyte percentage:
1. Viral infections: Such as Epstein-Barr virus (EBV), cytomegalovirus (CMV), rubella, and others, which often cause an increase in monocytes.
2. Chronic infections: Such as tuberculosis, syphilis, and brucellosis, which can stimulate increased monocyte production.
3. Monocytosis: A condition caused by EBV infection, characterized by a significant increase in monocytes.
4. Certain types of leukemia, such as acute monocytic leukemia or chronic myelomonocytic leukemia.
If an elevated monocyte percentage is detected, it is recommended to seek medical attention promptly.
