What are iron studies?
Iron studies are a group of blood tests that measure the amount of iron in your blood and how well your body is storing and transporting it. The main markers include serum iron (the amount of iron circulating in your blood), ferritin (a protein that stores iron in your cells), transferrin (a protein that carries iron through your bloodstream), and transferrin saturation (the percentage of transferrin that is carrying iron).
Together, these markers give your GP a comprehensive picture of your iron status. Iron is essential for producing haemoglobin, which carries oxygen in your red blood cells. Both iron deficiency and iron overload can cause significant health problems if left untreated.
Symptoms of iron deficiency
Iron deficiency is one of the most common nutritional deficiencies in Australia, particularly among women of reproductive age, vegetarians, and people with chronic conditions. Common symptoms include persistent fatigue, weakness, pale skin, shortness of breath, dizziness, cold hands and feet, brittle nails, and frequent infections.
If you are experiencing unexplained fatigue or any of these symptoms, iron studies can help determine whether low iron is the cause. Early detection allows your GP to recommend appropriate treatment, which may include dietary changes, iron supplements, or further investigation to identify the underlying cause of iron loss.
How to get an iron studies referral online
Book a telehealth appointment with a NewDoc GP and discuss your symptoms or concerns. If your GP determines iron studies are clinically appropriate, the pathology referral will be emailed to you after the consultation. You then attend any pathology collection centre in Australia for the blood draw.
Your GP may also order a full blood count alongside iron studies, as the two tests together provide a more complete picture of your blood health. The consultation is bulk billed for eligible Medicare patients, and the pathology tests are covered by Medicare when ordered on clinical grounds.
Understanding your iron studies results
Your NewDoc GP will review your iron studies results and explain what they mean. Low ferritin with low serum iron typically indicates iron deficiency, which is the most common finding. Elevated ferritin may indicate iron overload (haemochromatosis), inflammation, or liver disease. Your GP will interpret the results in the context of your symptoms and other test results.
If iron deficiency is confirmed, your GP may recommend oral iron supplements, dietary advice to increase iron intake, and follow-up testing in 6 to 12 weeks to check your response. In some cases, a referral to a specialist such as a gastroenterologist or haematologist may be appropriate to investigate the cause of iron loss.
