An increase in white blood cells in a complete blood count or CBC means there is an infection in the body. The severity of the infection depends on how high above normal the white count is and the severity of the accompanying symptoms.
A turning point is defined as a period in history when a significant change occurs. Three of these turning points were the neolithic revolution, the age of exploration, and the collapse of communism in the soviet union. The neolithic revolution was the process of shifting from hunting and gathering to farming and starting a civilization.
In fact, one of these conflicts can be considered the major turning point in the sense where a turning point is the maximum or minimum point on a curve (definition from free dictionary.com). It can also be said that the turning point is the point at which a very significant change occurs; a decisive moment.
