Causes of low neutrophils and high monocytes:

- Viral infections: Certain viral infections, such as influenza and measles, can cause a temporary decrease in neutrophils and an increase in monocytes.

- Bacterial infections: Some bacterial infections, such as typhoid fever and tularemia, can also cause low neutrophils and high monocytes.

- Autoimmune diseases: Autoimmune diseases, such as lupus and rheumatoid arthritis, can cause a decrease in neutrophils and an increase in monocytes.

- Certain medications: Some medications, such as chemotherapy drugs and corticosteroids, can cause a decrease in neutrophils and an increase in monocytes.
