What is

Ferritin is a complex globular protein that stores iron in an inactive form. It is found in many body cells, especially in the liver, spleen, bone marrow, and reticuloendothelial cells. It plays a significant role in the absorption, storage, and release of iron. As your iron stores deplete, the ferritin releases its iron for use. If your ferritin depletes, you will run out of iron and your ability to produce red blood cells in your bone marrow decreases.

What can I learn
from this test?

Our Ferritin Blood Test measures the amount of ferritin in your blood. Because ferritin stores iron, it estimates your body's iron levels and helps detect iron deficiency.

What could
my results mean?

If ferritin levels are low, additional tests, including an iron test, TIBC and transferrin test, are used to confirm a diagnosis of iron deficiency anaemia. Low ferritin levels indicate iron deficiency. Symptoms of iron deficiency include pale skin, fatigue, dizziness, and heart palpitations. High ferritin levels could indicate haemochromatosis (iron overload syndrome), an inherited condition where your body cannot rid itself of iron, so it accumulates over time. High ferritin levels are also associated with liver inflammation.

Iron status
Select profile for more information

Ferritin Ferritin is a protein which stores iron in your cells and tissues. Usually, the body incorporates iron into haemoglobin to be transported around the body, but when it has a surplus, it stores the remaining iron in ferritin for later use. Measuring ferritin levels gives us a good indication of the amount of iron stored in your body.
