  • Hypertransferrinemia

What does a high transferrin level in the blood mean?

Transferrin is a protein that carry iron through the blood.

A high transferrin level in the blood is a sign of iron deficiency. The liver, where transferrin is produced, tries to increase the production of transferrin to maximize the iron transport and compensate the iron deficiency.

A high transferrin value in the blood may suggest an iron-deficiency anemia.

  • Marked hypertansferrinemia (>360 mg/dL in adult men and >370 in adult women):

    The transferrin level in the blood is very high and it is probably that you are suffering from iron-deficiency anemia.

    For a better diagnosis, it is necessary to know the level of iron and ferritin in the blood. If both are low, this type of anemia for iron deficiency is the main possibility.

    In case of suffering from iron-deficiency anemia, you can feel fatigue, headache and difficulty breathing.

Which factors can raise the transferrin level in the blood?

There are some health circumstances or drugs than can raise your transferrin level in the blood:

Which diseases can raise your transferrin level in the blood?

There are different diseases why the transferrin level in the blood can be higher than normal:

What can I do to lower the transferrin level in the blood?

A transferrin high level in the blood is usually a consequence of lack of iron in the body. For that reason, the main tip is to increase the iron intake.

The following foods are rich in iron:

  • Red meat (pork, beef), liver.
  • Legumes: lentils, chickpeas.
  • Fish and seafood: Mussels, anchovies, sardines.
  • Fruits and vegetables: Peaches, spinach.
  • Eggs.

If you are taking oral contraceptives, it is advisable to talk to your doctor because they can alter the transferrin level in the blood.

IMPORTANT: These levels are expressed in mg/dL. They are an example of a healthy woman of about 45 years old with a balanced diet, not known disease and not taking any medication. The ranges can be different depending on the laboratory or on your personal circumstances.
