cause of elevated white blood count
What Causes High White Blood Cell Counts? White blood cell counts are elevated when the body is fighting an illness or disease, so a high count is indicative of an infection. Often, your doctor will order another round of tests after he or she determines you have a high white blood cell count.
A high count indicates the presence of inflammation in the body. Because white blood cells are calculated by the number of cells per volume of blood, test results can vary between labs. Different labs use different degrees of measurements for the white blood cell count.
