Serum Transferrin Concentration (Mass Concentration)

Why Might This Test Be Ordered?

Your healthcare provider may order this test to check for iron metabolism issues, such as iron deficiency or overabsorption. It can also help diagnose or monitor conditions like liver disease, kidney disease, or certain types of anemia. Sometimes, it’s used to evaluate nutritional status or response to treatment.

What Does a Transferrin Test Tell Us?

Transferrin levels can give clues about how well your body is using iron. Low levels might suggest iron deficiency or malabsorption problems, while very high levels could indicate conditions like liver disease or certain cancers. However, results alone don’t diagnose a condition—they’re part of a bigger picture.

How Is the Test Performed?

A blood sample is taken from a vein, usually in your arm. The blood is then sent to a lab to measure transferrin levels using a specialized test method. You may feel a small pinch when the needle is inserted, but the process is quick and usually painless.

What Do My Results Mean?

Your results will be compared to a reference range provided by your lab. While reference ranges can vary slightly by lab, they help determine if your transferrin level is within normal limits, low, or high. Your healthcare provider will discuss these results with you and explain what they mean for your health.
