Disease description:

A few days ago, my wife went to the hospital for a blood test. Today we received the report, which showed that her monocyte percentage is low. I would like to ask, what does a low monocyte percentage indicate?

A low monocyte percentage usually indicates the following possibilities: 1. Decreased immunity: Monocytes are part of the immune system, and a low percentage may suggest reduced immunity, making the body more susceptible to infections. 2. Chronic diseases: Hematologic diseases such as leukemia and tuberculosis may cause a decrease in monocyte percentage. 3. Excessive fatigue: Following prolonged熬夜 or heavy physical labor, the body may become overly fatigued, leading to a transient reduction in absolute monocyte count. 4. Infections: When the body is affected by bacterial or viral infections, a reactive increase in neutrophils or lymphocytes may result in a relatively low monocyte percentage. 5. Anemia: Anemia-related disorders such as aplastic anemia may lead to a reduction in monocyte count, resulting in a lower percentage. A low monocyte percentage should be evaluated in conjunction with specific symptoms and tests to identify the underlying cause and implement appropriate measures.
