About the test
What is this test done for?
The iron study is a blood test done to evaluate iron levels in the blood.
Why is it Done?
Iron is an important component of our body and its deficiency leads to anaemia. If the doctor suspects anaemia due to iron deficiency, then iron study tests might be ordered for confirming the diagnosis. Also, the test is performed to diagnose a condition called haemochromatosis characterized by high iron levels.
When should it be performed?
  • It should be performed when one has pale skin and mucous membranes like tongue, conjunctiva.
  • If one feels very tired or shortness of breath on exertion and postural light-headedness.
  • Other symptoms that demand this test are joint pains, low interest in sexual activity, heart problems.
How is it done
A blood sample will be collected from a vein in your arm. The person getting tested should be minimum 12 hours fasting before the test, but one can consume water if needed.
  • Positive results mean— Haemochromatosis, sideroblastic anaemia.
  • Negative results mean— iron deficiency anaemia, chronic bleeding disorders like ulcerative colitis, Crohn’s disease, etc.
