WBC counting is a test that determines how many white blood cells are present in the bloodstream. A complete blood count is usually used in conjunction with this examination. The term "white blood cell count" can also refer to the total proportion of white blood cells in the blood. WBCs come in a variety of shapes and sizes, and each kind is found in variable amounts in the blood. The white blood cell count, on the other hand, might occasionally fall or rise outside of the typical range. Let us explore the classification of WBCs and what is normal WBC count?

Types of white blood cells

The amount of white blood cells in the body is measured by a (WBC) count. White blood cells are divided into five categories:
•    Neutrophils are white blood cells that combat harmful bacteria. They typically account for 50 to 75 percent of all white blood cells.
•    Lymphocytes are immune cells that inhibit the growth of bacteria, stimulate the immune system, and eliminate malignancies. Both the blood and lymph tissues contain Lymphocytes.
•    Monocytes: Diseased or damaged cells are removed by monocytes. They move into tissues such as the liver and heart, where they transform into a different type of cell that acts as an antioxidant.
•    Eosinophils: Parasitic infections are combated by eosinophil. They also contribute to irritation and allergic responses.
•    Basophils: Throughout an allergic reaction, basophils emit a substance called histamine. This results in indications such as a stuffy nose and eye irritation.

Normal WBC count
The number of WBCs in the blood varies between 4,500 and 11,000 per microliter (4.5 to 11.0/mL).  The accepted value levels may change somewhat between laboratories. Some laboratories may examine different samples or utilize different metrics. Confirm your test results with the healthcare professional.
Some medications might cause an increase in the (WBC) count. Common medicines that can accomplish this include:
•    Lithium is a mood-stabilizing medication. It's being used to treat bipolar illness and chronic depression.
•    Heparin is a blood-thinning medication. It's used to keep blood clots at away.

Objective of the Test
White blood cells account for less than 1% of the total blood cells. They play an important part in maintaining the body's wellness. They are component of the immune and are produced in the bone marrow. It helps the body to fight against the pathogens and reduce inflammation. If the patient has the following signs and symptoms, the doctor may prescribe a (WBC) count:
•    Inflammation
•    Aches and pains in the body, as well as headaches
•    Sweats during night
•   Swelling in Lymph nodes
•    Spleen enlargement

Risks
Drawing blood from the vein carries minimal risk for the person. The thickness of veins and arteries varies among individuals and from one part of the body to the other. It may be more challenging to get a blood test from some persons than from others. Other dangers of having blood drawn are minor, although they might include:
•    Excessive bleeding (it is rare)
•    Feeling dizzy or lightheaded
•    Several punctures are required to detect veins
•    Blood clots under the skin, causing a hematoma
•    Possibility of infections on the punctured area
