Albumin is a protein made by your liver. Its main job is to stop your blood from leaking into other tissues, but it also helps transport hormones, vitamins, minerals and enzymes through your body, as well as aiding the tissue growth and healing. Abnormal levels of albumin in your body may indicate problems with your liver or kidneys.
Globulin is a type of serum protein found in your blood. It is used by your body to help regulate your circulatory system and transport metals in your blood, like iron, and help fight infection.
Your total protein is the combined total of albumin and globulin in your blood.
Iron is an essential mineral in your body which helps make healthy red blood cells. If your body doesn’t have enough iron, your cells won’t get enough oxygen and you will feel tired and lethargic.
Total Iron Binding Capacity (TIBC) measures your blood’s capacity to bind iron with transferrin, a protein which transports iron around your body. This will show you how much iron your body is able to carry through your blood.
