What does it mean if the monocyte percentage is low?

A low percentage of monocytes can be caused by various factors, including both physiological and pathological reasons. 1. Physiological factors: The number of monocytes in the peripheral blood of healthy adults is naturally low, typically ranging between 3%-8%. If the percentage of monocytes is only slightly decreased and the patient has no symptoms or discomfort, it usually has no clinical significance and does not require specific treatment. 2. Pathological factors: A reduced monocyte percentage may be related to infectious diseases (e.g., viral infections), hematologic disorders (e.g., hemolytic anemia, leukemia, myelodysplastic syndromes), and other conditions. These diseases may lead to a decrease in monocyte count, resulting in a lower percentage. The exact cause of a low monocyte percentage must be determined by evaluating the patient's specific symptoms and other laboratory findings. If there are concerns or noticeable symptoms, timely medical consultation is recommended.
