Only your doctor can diagnose iron deficiency anemia (IDA) and he or she will use specific blood tests to diagnose it. IDA is determined by testing three different parts of your blood: hemoglobin (Hb), ferritin, and transferrin saturation (TSAT).
If you do have IDA, your doctor will continue to use blood tests to keep an eye on your iron levels during treatment.
Common tests for diagnosing IDA
Click on each to learn more:
Hemoglobin (Hb)Hemoglobin is a protein in red blood cells that carries oxygen throughout the body. You can develop anemia when there are not enough red blood cells, or when the cells are not working properly.
FerritinFerritin is a protein inside your cells that stores iron. It allows your body to use the iron when it needs it. A ferritin test indirectly measures the amount of iron in your blood.
Transferrin saturation (TSAT)Transferrin is a protein responsible for transporting iron through your body. TSAT measures the amount of iron that is immediately available to produce red blood cells.
What your lab values mean
After your doctor orders a blood test, you will receive the lab results and you’ll likely want to know more about what they mean. This chart can help you understand. The chart shows “normal” values, but keep in mind that these can vary for many reasons, depending on the person, your medical condition(s), and where the test was taken.
IDA can be serious, so talk to your doctor
If your lab values are below normal range, talk to your doctor about the best option for restoring your iron levels.
The information on this website should not take the place of talking with your doctor or healthcare professional.
If you have any questions about your condition, or if you want more information about IDA or Injectafer,

- In children: low levels of phosphorous in your blood, pain or bruising at the injection site, rash, headache, and vomiting
Excessive amounts of Injectafer may lead to a condition called iron overload, which is a buildup of iron and may be harmful.
These are not all of the possible side effects of Injectafer.
Tell your doctor if you have any side effect that bothers you or that does not go away. Call your doctor for medical advice about side effects.
