Iron is an important mineral that plays a role in several metabolic processes in the body. At-home iron tests allow a person to check their iron levels without a doctor’s appointment.

Iron is an important mineral for the body. Research has shown that iron plays a vital role in several metabolic processes, including oxygen transportation in the blood, creation of blood cells, and hormone production.

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

Consuming insufficient amounts of dietary iron can result in iron deficiency. People who menstruate, are pregnant, or are breastfeeding require more iron, so they are more likely to have iron deficiency.

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

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

An iron test is often just one component of a general blood test, as laboratory technicians can run multiple tests on the same sample of blood.

When a doctor orders an iron test, they often order several tests at a 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 transports iron, in the blood.
  • Serum iron test: The serum iron test measures iron levels 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 is important to note that ferritin is a marker of inflammation, which is why certain conditions — such as chronic kidney disease, liver disease, cancer, and metabolic syndrome — can cause the test results to be falsely normal or elevated. Therefore, if a ferritin test shows normal levels of iron, but a person has the symptoms of iron deficiency, they should undergo further tests.

Alternatively, an individual can opt for an at-home testing kit that allows to perform more than one of the tests above.

Iron tests will return a result that tells a person whether their iron levels are normal, low, or high.

Low iron levels indicate a potential iron deficiency, whereas high levels suggest an iron overload. If an at-home test shows either condition, a person should consult a healthcare professional.

Iron deficiency

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

The signs and symptoms of iron deficiency anemia include:

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

Iron overload

When a person consumes too much iron, they are at risk of iron overload. Iron deposits increase in the liver, heart, and endocrine glands, and they 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 heritable, meaning that it can pass from parents to their children. However, a person will only experience symptoms if they receive one 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 test results show high iron levels or if symptoms of iron overload occur, a person should seek guidance from a doctor.
