Iron is an important mineral for the body.
Consuming insufficient dietary iron can result in an iron deficiency. People who menstruate or are pregnant or breastfeeding require more iron, so they are more likely to have an iron deficiency.
Certain health conditions can prevent a person from absorbing the iron that they consume,
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 normal amount of this mineral.
An iron test is often just one component of a general blood test, as lab 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 as ferritin is a marker of inflammation, certain conditions — such as chronic kidney disease, liver disease, cancer, and metabolic syndrome —
Alternatively, a person can opt for an at-home testing kit that performs 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.
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
- brittle nails
- pale skin
- cracks at the corners of the mouth
- chest pain
- shortness of breath
- restless leg syndrome
If a person gets test results that indicate low iron levels or experiences any symptoms of iron deficiency anemia, they should contact a doctor for further advice and treatment.
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.
The signs and symptoms of iron overload
- chronic fatigue
- abdominal pain
- high blood glucose levels
- irregular heartbeat
- low libido
Iron overload can either be primary or secondary, with the primary form being
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 symptoms of iron overload occur, a person should contact a doctor for further advice and treatment.

A person should interpret their results with the help of a healthcare professional. If a blood test shows that a person’s iron levels are too high or too low, a doctor will be able to offer advice and recommend any treatment options.
People should also contact a doctor if they are experiencing symptoms that are worrying, even if a blood test states that their iron levels are within a normal range.
The following are some frequently asked questions about taking an at-home iron test.
How do I use an at-home iron test?
At-home test kits come with instructions on how to take a sample. People should follow the manufacturer’s instructions carefully to ensure an accurate result.
However, many at-home tests require the following steps:
- Order a kit online or at a local pharmacy.
- Use the provided testing materials to perform a finger prick.
- Collect a blood sample.
- Send the sample to a lab.
- Wait for the results.
The company that provides the test kit will inform a person of their test results through its website or app. Some companies will offer follow-up phone calls to discuss results that reveal low or high iron levels.
A person should discuss their results with a healthcare professional to receive advice and find out about the treatment options.
Are at-home iron tests accurate?
At-home iron tests can be accurate. Users should follow all instructions to ensure that they are providing a valid sample.
Some people may wish to buy at-home tests that process samples in CLIA-approved or CAP-accredited labs. If a company sends the samples to these labs, it means that the technicians follow guidelines that reduce the risk of invalid test results.
Iron tests measure the amount of iron in the blood and how well the body absorbs it. The results may indicate an iron deficiency or an iron overload.
At-home tests may check for similar markers to a blood test that a doctor might order. When taking an iron test at home, a person should follow all of the instructions carefully and follow up with a doctor if they receive abnormal results.
