Non-phagocytic leukocytosis is probably due more to stimulation of blood-making organs than to chemotaxis.
In general, the response of the leukocytes to chemotaxis is a conservative process.
chemotaxis alone will not explain the continuance of leukocytosis for more than a short time.
chemotaxis means simply the effect of the presence of certain substances on vital organisms without specific chemical action.
chemotaxis che·mo·tax·is (kē'mō-tāk'sĭs, kěm'ō-)
The characteristic movement or orientation of an organism or cell along a chemical concentration gradient either toward or away from the chemical stimulus. Also called chemotropism.
