WBC

WBC stands for white blood cells, which are a key part of your immune system. They help your body fight infections caused by bacteria, viruses, fungi, and other pathogens. WBCs can move through your blood and tissues to identify and attack harmful invaders. A WBC count measures how many white blood cells you have, providing important information about your immune health. An elevated count may indicate infection or inflammation, while a low count could suggest a weakened immune system. Overall, white blood cells are essential defenders that help keep you healthy by protecting against illness.
