This blood test measures the level of iron, an important part of hemoglobin. An iron test can help your healthcare provider decide if you have too much or too little iron (iron deficiency) in your blood. It may be recommended if your healthcare provider suspects you have anemia due to too little iron or an inherited condition that causes high levels of iron in your blood (hemochromatosis). To find the cause of anemia, iron testing is often ordered with:

  • Total iron-binding capacity (TIBC)
  • Ferritin test (to assess your iron stores)

When done together, these tests can help determine if anemia is due to a lack of iron in the diet, blood loss or an illness.

In the beginning, low iron levels (anemia) often go unnoticed. As the iron level drops, some of the following symptoms can occur:

  • Feeling tired all the time
  • Dizziness and weakness
  • Headaches
  • Pale skin
  • Shortness of breath
  • Chest pain

The blood sample is usually taken by placing a needle in a vein in the arm or by pricking a finger.

  • Ask your healthcare provider if there are any specific instructions you need to follow before the test.
  • Ask your healthcare provider if you need to stop taking any medicines before the test.
  • Do not stop taking any medicine unless your healthcare provider tells you to do so.

This care path's costs do not include the charge to draw blood from a vein (venipuncture). There will only be one charge to draw blood, even if multiple tests are being performed on the samples that are taken.

What should I ask my healthcare provider before having this test?

  • Is there any special preparation for the test? (If so, get clear instructions on what you need to do.)
  • What is the reason for the test? Will the test results change my treatment plan? If not, do I need the test?
