Iron Levels Low? Discover the Key Tests You Need!
Published: Apr 19, 2024
Iron deficiency can be sneaky, but with the right tests, you can catch it early. Learn about the essential tests to check your iron levels and what they mean.
Understanding Iron Tests
Iron tests measure different aspects of iron in your body, such as serum iron, ferritin, and transferrin saturation. These tests help determine if you have enough iron and can pinpoint if there's a deficiency.
The Role of Ferritin
Ferritin is a protein that stores iron, and its levels reflect your body's iron reserves. Low ferritin levels are a key indicator of iron deficiency, even before other symptoms appear.
Interpreting Transferrin Saturation
Transferrin saturation measures how much iron is bound to the protein transferrin in your blood. Low levels suggest your body isn't transporting enough iron, which is often seen in iron deficiency anemia.
