What Are Leukocytes?
Leukocytes, also known as white blood cells, are an important component of blood and a key player in the body’s immune system. There are a number of different types of leukocytes, each with specific functions. An elevation in leukocytes in the blood can indicate the presence of infection or underlying disease, while leukopenia, in which these cells are reduced in number, can also be an indicator of a medical problem.
