Difference Between Ferritin and Transferrin

Ferritin is stored in the body's cells until it's time to make more red blood cells. The body will signal the cells to release ferritin. The ferritin then binds to another substance called transferrin. Transferrin is a protein that combines with ferritin to transport it to where new red blood cells are made.

What is the role of transferrin?

Transferrin is a blood-plasma glycoprotein, which plays a central role in iron metabolism and is responsible for ferric-ion delivery. Transferrin functions as the most critical ferric pool in the body. It transports iron through the blood to various tissues such as the liver, spleen and bone marrow.

Does ferritin bind to transferrin?

Iron in the labile pool that exceeds requirement for the synthesis of functional heme and nonheme iron-containing proteins is stored within the iron-storage protein, ferritin. ... Such a binding inhibits translation of ferritin mRNA and stabilizes the mRNA for transferrin receptors.

What is the difference between transferrin and TIBC?

Transferrin is a protein produced by the liver. It regulates the absorption of iron into the blood. TIBC relates to the amount of transferrin in your blood that's available to attach to iron.

What does transferrin level mean?

The normal range for transferrin is 170 to 370 mg/dl. If you have a higher amount, you may have iron-deficiency anemia. If you have a lower level, you may have another problem, such as liver disease and hemolytic anemia. Transferrin may also be measured using a value called total iron-binding capacity (TIBC).

What is a normal transferrin level?

The normal range for transferrin is 204 to 360 mg/dl. If you have a higher amount, you may have iron-deficiency anemia. If you have a lower level, you may have another problem, such as liver disease and hemolytic anemia.

Where is transferrin stored?

3.2.

Transferrin is a protein synthesized almost exclusively in the liver and is secreted into the blood. It is the principal transport protein for iron throughout the body and delivers approximately 70% to the bone marrow for incorporation into hemoglobin within RBCs. The remainder is stored in the tissue.

What is true about ferritin and transferrin?

transferrin - measures levels of the iron carrier; total iron binding capacity (TIBC) - measures the transferrin capacity to bind iron; serum ferritin - measures the body's ability to store iron.

How do you reduce transferrin saturation?

Dietary changes can include:

1. avoiding supplements that contain iron.
2. avoiding supplements that contain vitamin C, as this vitamin increases iron absorption.
3. reducing iron-rich and iron-fortified foods.
4. avoiding uncooked fish and shellfish.
5. limiting alcohol intake, as this can damage the liver.

Where is ferritin protein found?

101.2.

Ferritin is a ubiquitous protein found in all cells, where its principal function appears to be storage of iron. Ferritin concentrates cellular iron and protects cells from its toxic effects. Storage iron is sequestered in a hollow sphere composed of 24 ferritin subunits (7).

What happens if transferrin saturation is low?

Transferrin saturations of less than 20% indicate iron deficiency, while transferrin saturations of more than 50% suggest iron overload. Iron tests frequently performed together to diagnose iron deficiency or overload include serum iron, ferritin, IBC, and transferrin levels.

Is ferritin and iron the same?

Ferritin is a blood protein that contains iron. A ferritin test helps your doctor understand how much iron your body stores. If a ferritin test reveals that your blood ferritin level is lower than normal, it indicates your body's iron stores are low and you have iron deficiency.

What should ferritin levels?

The results may vary slightly among laboratories, but in general, normal ferritin levels range from 12 to 300 nanograms per milliliter of blood (ng/mL) for males and 12 to 150 ng/mL for females.
