White blood cell counts can also increase following exercise and in response to allergens, pregnancy and asthma, explains Healthline. Medications that can affect white blood cell counts include antihistamines, antibiotics, aspirin and corticosteroids. Symptoms that often accompany high white blood cell counts include fever, body pain and chills. Once the underlying cause of a high white blood cell count is determined, a treatment plan is put into place and individuals are typically required to undergo follow-up testing.

The five different types of white blood cells in the human body are neutrophils, basophils, monocytes, lymphocytes and eosinophils, according to MedlinePlus.

Low white blood cell counts can indicate certain cancers or liver diseases and bone marrow failure.
