Description
Transferrin Saturation % (Must do FE TIBC)
Sample Type: Serum
Tests Included:
Transferrin Saturation calculation using Iron and Total Iron Binding Capacity (TIBC) values
Sample Required:
Blood sample
Test Time:
Results are typically available within a few days.
Test Range Values:
Normal transferrin saturation levels are usually between 20% to 50%. Abnormal values can indicate iron deficiency or iron overload conditions.
What is the test?
Transferrin saturation is a calculation that assesses the proportion of transferrin (a protein that transports iron in the blood) that is saturated with iron. It is calculated using the values of serum iron and total iron binding capacity (TIBC).
Test Procedure:
Serum iron and TIBC are measured using a blood sample. Transferrin saturation is calculated using these values.
When to take the test:
When a healthcare provider suspects iron-related disorders, such as iron deficiency anemia or hemochromatosis, they may order this test.
Who should take the test:
Patients with symptoms suggestive of iron-related conditions, individuals with a family history of such conditions, or those undergoing iron supplementation may require this test for diagnosis and monitoring.
Precautions for exceptional cases (pregnancy, etc.):
Iron levels and transferrin saturation can be influenced by pregnancy. Pregnant individuals should inform their healthcare provider about their pregnancy status for accurate interpretation of the results.
Frequently Asked Questions (FAQs) for Transferrin Saturation % Test:
Q1: What does low transferrin saturation indicate?
A: Low transferrin saturation can indicate iron deficiency, where the body lacks sufficient iron to saturate the available transferrin. This condition can lead to iron deficiency anemia.
Q2: What does high transferrin saturation indicate?
A: High transferrin saturation can indicate iron overload conditions, such as hemochromatosis, where excessive iron is absorbed and stored in the body’s organs and tissues. This can lead to organ damage over time.
Q3: Can transferrin saturation fluctuate based on dietary changes?
A: Transferrin saturation levels are influenced by both dietary iron intake and the body’s iron storage and utilization. Changes in diet and iron supplementation can impact transferrin saturation levels.
