FERRITIN

The Ferritin test measures ferritin, the protein that stores iron inside your cells. While haemoglobin shows the iron currently in your blood, ferritin shows the iron in reserve — so it often drops before anaemia appears, making it the earliest warning sign of iron deficiency.

In Lucknow, ferritin is most commonly ordered for persistent fatigue, hair fall, pale skin, and restless legs — and during pregnancy and adolescence, when iron demand rises. It is also used to investigate iron overload conditions on a doctor's advice.

When do doctors advise this test?

• Persistent tiredness, weakness or pale skin suggesting low iron
• Hair fall or brittle nails where iron deficiency is suspected
• Pregnancy or adolescence — periods of high iron demand
• Follow-up after iron supplements, to check whether stores are rebuilding

Preparation & the sample

No fasting is required for the ferritin test. A blood sample is drawn and the serum tested by chemiluminescent immunoassay. Reports are issued the same day. Ferritin is often ordered alongside haemoglobin/CBC and iron studies — your doctor will specify the combination. Call +91 9451155402 to book a home sample collection in Lucknow.
