Iron testing: should I be tested?
Iron deficiency without anemia
Low iron is common. It can cause real symptoms even when your blood count looks normal. This is called iron deficiency without anemia. Symptoms include tiredness, restless legs, hair loss, or feeling short of breath with exercise. Some people crave ice or other non-food items. Ferritin is the best test for this. It is a blood test. It shows how much iron your body has stored. It makes sense to check ferritin if you have one of these symptoms. It also makes sense if you have a reason to be at risk. This includes heavy periods, pregnancy, a vegetarian or vegan diet, or a gut problem that affects absorption. If low iron is confirmed in a man or an older woman with no clear cause, your doctor may look for a source of blood loss in the gut.
Tests you may hear about
Hereditary hemochromatosis (iron overload)
Hemochromatosis is a genetic condition. Your body absorbs too much iron from food. Over years, the extra iron can build up. It can damage your liver, heart, joints, and hormone glands. It is real and treatable. But it is less common than people think. A high ferritin result alone does not mean you have it. Ferritin also rises with infection, obesity, fatty liver, or heavy alcohol use. These are all far more common than hemochromatosis. Real suspicion comes from a high ferritin plus a high transferrin saturation. It also comes from a close relative with hemochromatosis, unexplained liver disease, new diabetes, joint pain, or skin darkening. If these are present, a genetic test can confirm it. If a parent or sibling has confirmed hemochromatosis, ask about testing yourself, even without symptoms.

Worth asking
Questions you could bring to your doctor:
- Do my symptoms or risk factors mean I should have ferritin checked?
- Could inflammation be making my ferritin look normal when my iron is actually low?
- My ferritin came back high — does that mean I have hemochromatosis?
- What further testing would I need if both my ferritin and iron saturation are high?
- What new symptoms mean I should be tested again?
