Iron is an important mineral for the body. Research has shown that iron plays an important role in several metabolic processes, including the transport of oxygen in the blood, DNA production, and electron transfer.

There are two forms of food iron: heme and non-heme. Heme iron is a more absorbable form of this mineral and comes from animal sources such as meat, poultry, and seafood. Non-heme iron is less absorbable and comes from plant sources and foods fortified with iron.

Insufficient dietary iron intake can lead to iron deficiency. People who are menstruating, pregnant, or breastfeeding need more iron, so they are more likely to be iron deficient.

Certain health conditions can prevent a person from absorbing the iron they consume, including:

Iron tests can check how much iron is in the blood. The results may indicate that a person has too little, too much, or a normal amount of this mineral.

An iron test is often only one component of a general blood test, as lab technicians can perform multiple tests on the same blood sample. When a doctor orders an iron test, they will often order multiple tests at the same time. The combined results can help a doctor determine whether a person has low, normal, or high levels of iron in their blood.

Iron tests can include:

  • Transferrin test: This test measures the amount of transferrin, a protein that carries iron, in the blood.
  • Serum iron test: The serum iron test measures the iron level in the liquid part of the blood.
  • Total Iron Binding Capacity (TIBC) Test: The TIBC test checks how well iron binds to transferrin and other proteins.
  • Ferritin test: This test measures the amount of iron that the body stores.

It’s important to note that because ferritin is a marker of inflammation, certain conditions – such as chronic kidney disease, liver disease, cancer, and metabolic syndrome – can cause test results to be incorrectly normal or elevated. If a ferritin test shows normal iron levels but a person has symptoms of iron deficiency, they should have additional tests.

Alternatively, a person can opt for a home test kit that will perform more than one of the tests listed above.

Iron tests return a result that tells a person whether their iron level is normal, low, or high. Low iron levels indicate a possible iron deficiency, while high levels indicate iron overload.

Iron deficiency

Iron deficiency occurs when a person does not have enough iron in their body. It can lead to iron deficiency anemia.

Signs and symptoms of iron deficiency anemia include:

If a person gets test results that indicate low iron levels or have symptoms of iron deficiency anemia, they should contact a doctor for further advice and treatment.

Iron overload

If a person ingests too much iron, there is a risk of iron overload. Iron deposits increase in the liver, heart and endocrine glands and can cause organ damage.

Signs and symptoms of iron overload include:

Iron overload can be either primary or secondary, with the primary form being more common. Primary iron overload is inheritable, meaning it can be passed from parents to their children. However, a person will only experience symptoms if they receive a copy of the faulty gene from each parent.

Secondary iron overload can result from excessive dietary protein consumption, long-term kidney dialysis, certain types of anemia, or chronic liver disease.

If the test results show high iron levels or symptoms of iron overload occur, a person should contact a doctor for further advice and treatment.
