A normal WBC count is, as I wrote, anywhere and everywhere from 4.5 to 10.0 but during pregnancy those normal values can be between 6 and 16 in the third trimester and may reach 20 to 30 in labor and in early postpartum.
Normal in this context means that 95 percent of the healthy population is within that range, which implies that about 2.5 percent of healthy people will have a white blood cell count over 11,000. Many conditions cause the WBC count to increase temporarily, especially infection. However, if the condition is persistent, then the first step in understanding why is to determine which type of white blood cells has increased.
