Description

What is the purpose of this test?

Order this Transferrin Blood Test, which screens for iron deficiency or excess and diagnoses anemia by measuring transferrin levels in the blood. Transferrin is a glycoprotein found in the blood that is vital in transporting iron throughout the body. It binds to iron and carries it to the different parts of the body that require it. A transferrin test is a diagnostic examination that measures the level of transferrin in the blood. It is also possible to indirectly calculate the level of transferrin, known as the total iron binding capacity (TIBC). TIBC is the amount of iron transferrin that can bind to and is expressed in micrograms per deciliter (mcg/dL).

 

A transferrin and iron-binding capacity test may be ordered if an individual has a low hemoglobin and hematocrit on a complete blood count (CBC). These tests may also be ordered if a healthcare practitioner suspects that an individual may have too much iron (overload) or too little iron (deficiency) in their body. The test results can be used to support a diagnosis and help guide appropriate treatment.

 

When should I order a Transferrin Blood Test?

Individuals may order this test if they have experienced symptoms related to anemia. Common signs or symptoms of anemia include:

 

  • Chronic fatigue
  • Dizziness
  • Weakness
  • Headaches
  • Pale skin
