Soluble Transferrin Receptor Test
Soluble Transferrin Receptor Test: Iron Deficiency and Anaemia Marker
Direct answer: The soluble transferrin receptor (sTfR) test measures transferrin receptor levels in blood to help assess iron deficiency and differentiate types of anaemia.
Soluble transferrin receptor is a protein released into blood when body cells demand more iron. Higher sTfR levels usually indicate iron deficiency, even when routine iron tests appear normal. This test is advised when unexplained anaemia, fatigue or low haemoglobin levels need further evaluation. Sample collection is available through our Home Collection Facility across Pune or at our Direct Walk-in Facility in Aundh and nearby areas.
Why is the sTfR test advised?
Direct answer: This test helps confirm iron deficiency and distinguishes it from anaemia of chronic disease.
sTfR measurement supports accurate identification of iron-deficiency anaemia when standard iron studies are inconclusive. Doctors may interpret results along with ferritin and complete blood count reports. Learn more about blood health testing in our health articles, view sample guidance in test preparation guides, or compare anaemia-related health profiles on comparison resources.

Frequently Asked Questions
When should I do a soluble transferrin receptor test?
This test is advised when anaemia is detected and doctors need to confirm iron deficiency or differentiate other anaemia types.
Is fasting required before this test?
Fasting is not required. You may continue normal food and water intake before sample collection.
What does a high sTfR level indicate?
High sTfR levels usually suggest iron deficiency and increased cellular iron demand.
Which symptoms may lead to this test?
Fatigue, pale skin, shortness of breath, dizziness or persistent weakness may prompt this test.
