Ask the Pathologist - MCQ of the Week, No. 1. A short question to test how well you know common laboratory tests, with a plain-English explanation from Dr B.C. Gupta, MD (Pathology).
Q. Which test is most useful for assessing iron stores in suspected iron-deficiency anaemia?
- A. Serum Calcium
- B. Serum Ferritin
- C. Serum Bilirubin
- D. Serum Uric Acid
Answer: B. Serum Ferritin
Serum ferritin generally reflects the body’s iron stores and is an important investigation when iron deficiency is suspected. Iron deficiency is a common cause of anaemia, and a low ferritin level supports that diagnosis.
Ferritin should be interpreted along with the clinical picture and other blood tests, because its level can be affected by conditions such as inflammation. Your doctor will look at the complete result, not just a single value.
If you have been asked to check for anaemia or iron deficiency, a blood test is simple and quick. Call the centre to confirm preparation and timing before you visit.
