Silent Signals: Are You Tired, or Is It Iron Deficiency?

Diagnostic Blood Testing
For a definitive diagnosis, a doctor will order a Complete Blood Count (CBC) to check hemoglobin and red blood cell levels. Furthermore, a Ferritin test is vital as it shows the level of the body's iron stores. In the early stages of iron deficiency, hemoglobin may be normal while ferritin levels drop, indicating the depletion of iron stores has begun.
