Ferritin is a protein that stores iron and releases it in a controlled fashion. Ferritin typically lies in the cells of the liver (hepatocytes) and immune system (reticuloendothelial cells). When the body releases ferritin, it goes and binds to transferrin. Transferrin is a protein that helps to transport ferrin to where the new red blood cells are made. A serum ferritin test indicates the amount of iron stored in the body. This is a very important test because it helps to distinguish between iron deficiency anaemia and anaemia of chronic disease.
- High levels of ferritin: Hemochromatosis, Alcoholic liver disease
- Low levels of ferritin: Anaemia, Heavy menstrual bleeding
- Iron rich sources
- Vitamin C rich sources
- Iron cannot be absorbed in the body, if there are medical conditions such as:
- In case of kidney disease, the kidneys are unable to make enough hormones that signal the body to make red blood cells.
- Tannins present in coffee, tea can inhibit the absorption of non heme iron.
