If the number of WBCs is elevated above 10 000/µL there is ''leukocytosis''. The body produces more WBCs in response to most infections and inflammations in the body. An elevated white blood count on a blood test is almost always indicative of an ongoing infection or inflammation in the patient. In theory strenuous exercise and emotional stress can cause leucocytosis too.

If the number of WBCs is below 4 000/µL there is ''leukopaenia''. This occurs if there is damage to the bone marrow, due to toxic effects from drugs, [[radiation]], [[chemotherapy]], or cancer of the bone marrow, such as [[myelodysplastic syndrome]] or [[leukaemia]].

This occurs if there is damage to the bone marrow, due to toxic effects from drugs, [[radiation]], [[chemotherapy]], or cancer of the bone marrow, such as [[myelodysplastic syndrome]] or [[leukaemia]]. If a complete blood count has revealed that there are pathologically low levels of all blood cells, the condition is called [[pancytopaenia]].
