There are several kinds of white blood cells WBCs , including neutrophils, eosinophils, lymphocytes, monocytes and basophils. Each variety plays a different role in protecting the body from foreign pathogens such as viruses, bacteria, fungi and parasites.
White blood cells also defend the body from allergens, mutated cells, such as cancer, and foreign matter, such as splinters, and remove dead cells, old red blood cells and other debris. A white blood cell count checks both the overall levels of white blood cells in the blood, as well as the overall proportion of different types of white blood cells.
A low white blood cell count can be caused by issues including: [2]. A low white blood cell count may cause symptoms such as fever, chills, headache and bodyache. If you are experiencing symptoms that may be related to a low white blood cell count or one of the underlying conditions associated with it, begin your personal health assessment with the Ada app now.
This can be related to: [3]. In most instances, there are no specific symptoms related to an elevated white blood cell count, though symptoms associated with the underlying medical condition may occur. However, in extreme cases, such as when leukocytosis occurs because of a condition affecting the bone marrow, symptoms directly related to an elevated white blood cell count may occur.
If you are experiencing symptoms that may be related to a high white blood cell count or one of the underlying conditions associated with it, begin your personal health assessment with the Ada app now.

An abnormally raised white blood cell count is not a disease condition, but can point to another underlying cause such as infection, cancer or autoimmune disorders. An abnormally high white blood cell count should always be considered for its possible causes.
Not every elevated white cell count is a problem, since it may represent a normal finding in response to an infection, which settles with time. However, if the elevated count persists then a doctor may decide that it requires further investigation to rule out other undiagnosed conditions.
Since leukopenia is itself asymptomatic and chronic infection may go unrecognised because of failure to mount a symptomatic response, immunocompromised patients will usually have a periodic blood count to monitor their white cell count along with other regular health checks.
