Preparation
Ferritin is the protein that stores iron inside your body — measuring it is the single best blood test for answering "are my iron stores adequate?" Haemoglobin can look normal while ferritin is quietly empty; that hidden deficiency is one of the most common causes of fatigue, hair fall and poor exercise tolerance, especially in Indian women.
Low ferritin means the iron tank is draining — from heavy periods, poor dietary absorption, or gut losses — and it should be refilled, not just tolerated. High ferritin is equally informative: it can reflect inflammation, liver fat, or iron overload, each needing a different response.
The test is a single home draw, no fasting needed, processed at an NABL-grade partner laboratory. Read it alongside your CBC (book together — one draw serves both) so your doctor sees stores and blood counts in the same glance.
Yes, and it often is. Haemoglobin stays normal until stores are nearly empty. Low ferritin with normal haemoglobin is "iron deficiency without anaemia" — it still causes fatigue and hair fall, and still deserves treatment.
