Iron deficiency marker

Transferrin saturation

Transferrin saturation measures the amount of iron bound to transferrin in the blood. Together with other markers, transferrin saturation can be used to investigate and monitor iron deficiency/excessive iron absorption.

What is transferrin saturation (iron saturation)?

Transferrin saturation (also called iron saturation) is a blood test used to measure the amount of iron bound to transferrin, a protein that carries iron in the blood.

What can a low or high transferrin saturation (iron saturation) mean?

A low transferrin saturation can be seen in iron deficiency. If you have an excess of iron (as in, for example, hemochromatosis), an elevated transferrin saturation is seen. Transferrin saturation can be affected in various diseases and conditions.

Transferrin saturation is calculated with the formula Iron/TIBC*100. Normally, transferrin is saturated with iron to about 30%.

Blood sample
How does the blood test take place?
Sampling for this test is done via a venous blood sample. The sample is usually taken from a vein in the crook of the elbow and is performed by trained healthcare professionals. How much blood you are allowed to give depends on the number of health markers to be analyzed. The sampling usually takes a few minutes.
Fasting
Fasting

This test requires you to fast before sampling. Fasting means that you are not allowed to eat or drink anything for at least 10 hours before your scheduled time for sampling. However, a glass of water is fine to drink during the fast. Any medications are taken as usual unless your doctor has given other instructions.
