Slightly high absolute monocyte values due to physiologic factors are not important; high absolute monocyte values due to pathologic causes such as infections require medical attention. 1. The normal absolute value of monocytes in adults is about (0.12~0.8)x10^9/L, which may vary from laboratory to laboratory. Infants and children may have higher monocyte levels than adults, which is physiologic and normal. 2. Slightly elevated monocyte levels in adults may be due to factors such as overwork, cold and hot environments, etc., and are also normal. It does not matter, but it is recommended that a review be conducted after a certain period of time to completely exclude pathologic causes. 3. For slight pathologic factors such as infection, resulting in a slight increase in the absolute value of monocytes, it is necessary to treat the cause of the disease, such as streptococcal infections can be treated with semi-synthetic penicillin such as cefuroxime. It does not matter if the index is slightly abnormal for a short period of time, but if it is elevated for a long period of time, it is recommended to go to the hospital in time to avoid delaying the condition.
