Blood contains vital cells and substances that keep humans alive.
In routine laboratory tests, also called blood work, blood is analyzed to provide information about a patient's health. The red blood cells' function is to carry oxygen around the body. Oxygen is first picked up in the lungs, and then it attaches to a molecule known as hemoglobin, which is inside a red blood cell. Platelets help with the clotting process to prevent bleeding, and the white blood cells fight infection. All of these cells need to be present in adequate numbers for a person's body to function properly.
