What is low transferrin level in the blood called?

  • Hypotransferrinemia

What is the normal transferrin level in the blood?

If you need to know which are the transferrin reference ranges or you require more information about the role of transferrin in the blood, you can visit normal transferrin level in the blood

What does a low transferrin level in the blood mean?

Transferrin is the protein that carries iron through the blood. The transferrin is produced in the liver and a low value of transferrin in the blood may be a sign that the liver's production of transferrin is not appropriate.

A low value of transferrin in the blood can be consequence of multiple disorders such as infections, inflammations, some types of cancer or kidney or liver problems.

In many cases, it may suggest a secondary anemia caused by a chronic disease. In that case there will be other assays altered, for example, hemoglobin low in the blood.

If you are suffering from hemochromatosis, iron and ferritin in the blood will be high and transferrin low.

  • Mild hypotransferrinemia (150 - 215 mg/dl in adult men y 150 - 245 mg /dl in adult women):

    Transferrin level in the blood is a bit low. It may be a consequence of an infection or an inflammation.

    It is advisable to study other blood tests related to iron such as serum iron or ferritin to know if it is a casual alteration or if there is a problem with the iron in the body.

    If there is an alteration of ferritin and serum iron you should talk to your doctor. If only transferrin is altered, it may be due to some drugs and it is probable that in the next blood test the transferrin return to normal range.

  • Marked hypotransferrinemia (10 - 150 mg /dl in adults):

    Transferrin level in the blood is very low and the transport of iron trough the blood may be affected. It may be a sign of liver or kidney disorder.

    Low values of transferrin in the blood may cause iron accumulation in some organs (heart, liver) and provoke a cardiovascular disease.

  • Severe hypotransferrinemia (<10 mg/dl in adults):

    Severe hypotransferrinemia can alter the correct transport of iron through the body.

    There is a rare genetic disease, called congenital atransferrinemia, which is characteristic of severe hypotransferrinemia. It can be treated by transferrin blood transfusions.

Which factors can reduce the transferrin level in the blood?

There are some circumstances than can reduce your transferrin level in the blood:

  • Iron poisoning
  • Malnutrition
  • Drugs
    • Bacteriostatic agent
      • Chloramphenicol
    • Glucocorticoids
      • Adrenocorticotropic hormone

Which diseases can reduce your transferrin level in the blood?

Lower than normal level of transferrin in the blood can be due to:

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

A low level of transferrin in the blood is usually a secondary consequence of a chronic disease. The best way to revert the transferrin alteration is to find the primary disease and treat it.

Which values are considered a low transferrin level in the blood?

The following values are considered to be below the normal range:

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.
