What is the differential of leukocytes?
Complete blood count (CBC) is a test that is often used in evaluating individuals for different diseases. Part of the CBC is the differential of leukocytes, also called the differential of white blood cells (WBC), which calculates the number of WBC types present in a blood sample. WBC types include neutrophils, eosinophils, basophils, lymphocytes and monocytes. These cells are usually produced in the bone marrow, oily tissues found in large bones. Information about increasing or reducing any of these cells can help doctors diagnose and monitor their patients' reaction to treatment.
WBC types that count in the number of leukocytes have certain specific functions. Neutrophils help physical combat against infections caused by bacteria and fungi. If the number of neutrophils increases, bacterial infections are usually suspected. Reduction often reveals serious infection or may also be caused by side effects of cancer. Eosinophils are WBCs that often increase in parasic casesTical infections and allergies.
Lymphocytes are important in the production of antibodies, cells that fight with anything foreign that enters the body. Increasing lymphocytes is often an indication of virus infection, bone marrow disorders and leukemia. Lymphocyte reduction is often observed in individuals with immune system disorders such as lupus. Lupus is a disease in which the cells of the immune system attack other cells in the body. In some cases, leukemia also increases the number of monocytes and basophils in the leukocyte differential.
During the test, phlebotomist, individuals trained to use blood samples, usually extract blood from the patient's vein. Some patients may feel a little pain or discomfort during the process. No preparations are generally necessary before the number of leukocyte differentials. However, it is recommended that patients inform their doctor if they are taking some medicines because some medicines may affect the number of LEUkocytes. For example, the use of steroids for a long time can lead to an unusual outcome.
Some risks associated with the process of using blood sample include bleeding and infection from the wound site. There are also several patients who feel light during and after the procedure. Hematoma may also develop, which is the accumulation of blood in the skin.
