Transferrin Blood Test

Sample Report
Specimen Type: Blood


Transferrin Blood Test

Transferrin is a protein largely produced by the liver which binds to Iron and transports it throughout the body.  It is responsible for 50%-70% of the iron binding capacity of serum.  As there are other iron binding proteins, Transferrin is not the same as Total Iron Binding Capacity (TIBC).  Healthy liver function and nutrition are important to the body's ability to produce transferrin in the proper amount.  Transferrin levels increase in cases of iron deficiency and decrease in cases of iron overload.  An out of range Tranferrin level can be indicative of Iron Deficiency Anemia as well as a variety of liver problems.  Transferrin levels may not be elevated in cases of iron deficiency which are coupled with severe protein malnutrition.  Higher transferrin levels may occur in people taking oral contraceptives or in the late stages of pregnancy.   

A transferrin test may be ordered to monitor liver function or nutritional status.  When evaluating iron levels, Transferrin is often ordered with an Iron and Total Iron Binding Capacity (TIBC) test.

Turnaround time for this test is typically one business day.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.


The Transferrin test requires fasting for 8-12 hours prior to going in for blood collection.
