Iron (Serum): Iron is a mineral your body needs to make healthy red blood cells, which carry oxygen throughout your body. The iron lab test measures how much iron is circulating in your blood at the time of the test. If iron is low, it may mean your body doesn’t have enough to make strong red blood cells, which can cause fatigue, weakness, or anemia. If iron is high, it could mean your body is storing too much, which may stress the liver and other organs. This value is usually looked at alongside other tests (like ferritin, transferrin, and total iron binding capacity) to get the full picture of your iron and overall blood health. | Patient Information Leaflet (PIL): https://www.askdrskip.com/hemevite-plus/
