Normal White Blood Cell Count

It’s important to know what is considered a normal white blood cell count. If you’re in the hospital, your doctor might order a white blood cell test. It will measure the number of white blood cells that you have per volume of blood. If the results show a high amount, it is likely that you have an infection, inflammation, or allergy. Read the following list to learn more information about normal white blood cell counts.

Normal Range   For adult males and females, a normal white blood cell count ranges from 4,500 to 10,000 cells. This amount will decrease slightly with age. In order to determine blood cell counts, there are two different measurements that are taken. First, the test will figure out the amount of white blood cells that you have in a microliter of blood. The second part of the test will take percentages.

Lifespan  White blood cells begin when they are released from your bone marrow. They go into the peripheral blood. During this time, they are called a band. They produce and transport antibodies. The average lifespan of a white blood cell is thirteen to twenty days. After their lifespan has ended, they get destroyed in the lymphatic system.

Newborns  When they are first born, babies have a high white blood cell count.  It can range anywhere from 9,000 to 30,000 different leukocytes. However, those numbers tend to lower rather quickly. Within two weeks, the numbers have dropped to a normal white blood cell count. They end up with the same amount that adults have.

Low Count   If a white blood cell count drops below 4,000, leukopenia will occur. There are a number of disorders that can cause the normal white blood cell count to drop. For instance, it may be the result of a viral infection, bacterial infection, or a bone marrow disorder. If someone gets leukopenia, it is essential that they are protected from anything that will interrupt their skin integrity. Therefore, they are not able to have intramuscular injections or enemas.

Critical Values   A normal white blood cell count ranges from 4,500 to 10,000. Some people fall way below this. If a person has reached the critical value of less than 500 white blood cells, they have a high risk of getting a fatal infection. If someone has a white blood cell count that is over 30,000, they have a serious infection or disease. For example, leukemia patients often demonstrate this kind of high white blood cell count.
