Vacuolization may be present in a cell that has recently phagocytized foreign matter. A monocyte count is part of a complete blood count and is expressed either as a ratio of monocytes to the total number of white blood cells counted, or by absolute numbers. Both may be useful in determining or refuting a possible diagnosis. Monocytosis is the state of excess monocytes in the peripheral blood.
The absolute monocytes blood test measures the percentage of monocytes in relation to all white blood cells. A high level of monocytes could mean a number of things. They're a type of phagocyte - a type of cell found in your blood that 'eats' many types of attacking bacteria and other microorganisms when it matures. High levels could mean that you have an infection as more develop to fight it. However, if there's no trace of infection it could mean you have an auto-immune disease or a whole host of other things. It really depends on the other blood results as to determining what you have and what treatment you'll receive.
