WBC stands for White Blood Cell. White blood cells are a type of blood cell that plays a crucial role in the body's immune system. They help to defend the body against infection and disease by recognizing and destroying foreign substances, such as bacteria and viruses.
There are several types of white blood cells, each with a different function in the immune system. Abnormalities in white blood cell number or function can indicate a range of medical conditions, including infections, inflammatory diseases, and leukaemia.
The number and types of white blood cells in the blood can be measured through a simple blood test called a complete blood count (CBC). A CBC can provide information about the total number of white blood cells in the blood, as well as the relative proportions of different types of white blood cells, such as neutrophils, lymphocytes, and monocytes.
