White blood cell (leukocyte)

White blood cells are made in the bone marrow and protect the body against infection. If an infection develops, white blood cells attack and destroy the bacteria, virus, or other organism causing it.

White blood cells are bigger than red blood cells and normally are fewer in number. When a person has a bacterial infection, the number of white cells can increase dramatically.

The white blood cell count shows the number of white blood cells in a sample of blood. A normal white blood cell count is between 4,500 and 11,000 cells per cubic millimeter (4.5 and 11.0 x 109 cells per liter). The number of white blood cells is sometimes used to identify an infection or to monitor the body's response to treatment.

There are five types of white blood cells: lymphocytes, monocytes, neutrophils, basophils, and eosinophils.

Due to the threat of the COVID-19 (Coronavirus), we are taking precautionary measures to protect our staff and patients. We are implementing a temporary NO VISITOR policy at this time. Only patients or patients and their guardians will be allowed into the office. Please note, this is not to inconvenience anyone! The virus is a very real threat and it is essential that we stay healthy in order to provide needed care for our patients. If you are sick, we ask that you CALL the office to speak with a nurse before you come in. The nurse will provide specific instructions for you. Please DO NOT enter the office if you are sick (upper respiratory symptoms, fever, cough, or flu like symptoms). We are closely monitoring the situation and will update you as circumstances change. Thank you for your understanding!!
