Monocytes are the largest in size of the five types of white blood cells. Infection or acute stress increases the number of white blood cells which play a vital part in the immune system. Monocytes move to sites of infection and signal the immune system that a response is needed and are responsible for eliminating foreign substances. The absolute monocytes blood test measures the percentage of monocytes in relation to all white blood cells.
