High TIBC level in the blood

What is high TIBC level called?

  • TIBC high

What is the normal TIBC level in the blood?

If you need to know which are the TIBC reference ranges or you require more information about the role of TIBC in the blood you can visit: Normal TIBC level in the blood

What does a high TIBC mean?

TIBC is the acronym of Total Iron Binding Capacity. TIBC is a screening test to know the amount of iron that transferrin can bind. The transferrin role is to carry iron trough the blood.

TIBC is an indirect method to know the transferrin present in the blood. It is used because it is easier and cheaper than measures the transferrin in the blood directly.

A high TIBC value may be a sign of iron-deficiency anemia. In that case, iron level in the blood will be lower than normal.

  • Marked TIBC increase (>l;460 µg/dL in adults):

    If TIBC test shows excessively high values it may suggest an iron-deficiency anemia. To get a better diagnosis, it is recommended to study iron and ferritin in the blood. If both are lower than normal, it is probably that you suffer an iron-deficiency anemia.

    Other reasons for an increase in the TIBC are taking oral contraceptives or to be in the last trimester of pregnancy.

Which factors can raise the TIBC?

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

  • Pregnancy
  • Drugs
    • Oral Contraceptives
    • Fluoride

Which diseases can raise your TIBC?

The most common disease why the TIBC can be higher than normal is:

  • Iron-deficiency anemia

    What can I do to lower the TIBC?

    To reduce TIBC, you need to reduce transferrin level in the blood. For this matter is necessary an adequate intake of iron in the diet.

    The following foods are rich in iron:

    • Red meat (pork, beef)
    • Legumes (lentils, chickpeas)
    • Nuts (pistachios, almonds)
    • Spinach

    If your doctor considers it appropriate, he may prescribe you iron supplements.

    If you are taking oral contraceptives (birth control pills), you should tell your doctor because they can interfere in the TIBC.

    Where can I find more information about TIBC level in the blood?

    Which values are considered a high TIBC level in the blood?

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

    IMPORTANT: These levels are expressed in µg/dL. They are an example of a healthy woman of about 45 years old with no known disease and not taking any medication. The ranges can be different depending on the laboratory or on your personal circumstances.
