Talk to your provider about your test results. A low number of WBCs is called leukopenia. A count less than 4, cells per microliter 4. Neutrophils are one type of WBC. They are important for fighting infections. A higher than normal WBC count is called leukocytosis. It may be due to:. There is little risk involved with having your blood taken.
Veins and arteries vary in size from one person to another, and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others. Other risks associated with having blood drawn are slight, but may include:.
Differential leukocyte count Diff - peripheral blood. Laboratory Tests and Diagnostic Procedures. Basic examination of blood and bone marrow. The number of white blood cells in the body differs between individuals or at different ages in their lives. 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. The white blood cell count will typically return to normal around four-weeks after delivery. A normal white blood cell count is a reading that falls within a range established through the testing of men, women and children of all ages.
Although it is possible to cite general values, exact ranges tend to differ between labs and countries. However, some people have a specific disease in which only one type of white blood cell is affected. If levels of one particular type of white blood cell increase, this may be due to a specific trigger:.
There is, on occasion, no identifiable cause for the increase in white blood cells. This is known as idiopathic hypereosinophilic syndrome. It can lead to serious complications, such as damage to the heart, lung, liver, skin, and nervous system. White blood cell levels increase significantly during healthy pregnancy because of the physical stress the body endures during this time. The levels start to rise within the first trimester and continue to rise into the third trimester. During labor and in the hours following delivery, white blood cell levels may surge again, to between 9, and 25, white blood cells in every microliter of blood.
This is in response to the physical stresses and trauma of labor. Within 6—8 weeks of delivery, white blood cells return to their normal levels. A doctor may use a blood test to determine levels of white blood cells. If levels of white blood cells are lower than usual, this may be a sign that the person has reduced immune activity. This can occur as a result of conditions similar to HIV , or immunosuppressant medications.
A deficiency of white blood cells is why people with conditions or medications that suppress the immune system have an increased risk of infection. A number of conditions, collectively known as myeloproliferative disorders, can occur in the bone marrow. These develop when too many immature blood cells are produced, leading to an imbalance.
Myeloproliferative disorders are rare conditions that may or may not become malignant. The exact effects of a high white blood cell count depend on the condition or factor causing them. After noting any symptoms, a doctor can use a blood test to assess the white blood cell count, and further tests and examinations will often be necessary to pinpoint the exact cause of the problem.
A high white blood cell count may indicate several things, such as the immune system is working to destroy an infection, a sign of physical or emotional stress, or particular types of cancer.
Pregnancy also leads to high white blood cell count, as levels tend to rise from the first trimester, into the third. White blood cell levels will also rise in the hours following labor, due to the severe stress the body undergoes.
