Transferrin Saturation is a calculated value whereby the iron concentration is divided by total-iron binding capacity to produce an estimate of how many of transferrin iron-binding sites are being used. This calculation is called transferrin saturation.
In normal iron status, transferrin is usually one-third saturated with iron, so roughly two-thirds of its capacity is held in reserve. The iron concentration may be divided by the transferrin concentration, not the TIBC. This similar estimate is usually called the transferrin index.
Recent blood transfusions, iron injections and transfusions can all affect the results of iron tests.

The day before the test If you take iron supplements, avoid them for 24 hours before doing this test.
The day of the test Remember to take I.D. with you when going to take a test. Take this test before 10 am. If you are a woman who has menstrual cycles, it can be helpful to note down the day of your cycle.
What happens next?
The lab sends the results to your personal dashboard, with comments from both a doctor and a nutritionist. If results are abnormal, we recommend seeing a doctor and, if appropriate, booking an appointment with a Nordic Wellth nutrition lifestyle specialist.
You may need to make lifestyle and dietary changes.
Why test Transferrin Saturation %?
A diet low in iron, vitamin B12 and folate increases the risk of iron deficiency anemia (IDA).
Discover your risk factors for lifestyle diseases in time to do something about them.
Monitor changes to your blood values as you make lifestyle changes, take supplements, or undergo treatments.
A personal or family history of anemia or excess iron.
Heavy periods increase blood loss, and thus the risk of anemia.
Pregnant women are at increased risk of anemia. Healthy iron levels are important for both mother and baby.
Iron is involved in muscle function, transporting oxygen to the tissues, and the conversion of carbohydrates into energy.
Including low energy, fatigue, rapid heart rate (especially with exercise), dizziness, pale skin, leg cramps, insomnia, joint pain, stomach pain, liver disease, or skin changes.
You take a drug, such as hydrocortisone or antacids, which increases the need for iron.
