The biggest flaw in modern women’s healthcare is relying solely on a standard Routine Blood Count (FBC) to check for anemia. A standard blood screen only measures hemoglobin—the iron currently circulating in your red blood cells. However, your body will completely drain its hidden iron storage tanks (ferritin) to keep your hemoglobin looking perfectly normal on paper. If your doctor does not specifically order a Serum Ferritin Test, a severe deficiency will be completely missed. For anyone experiencing heavy menstrual flow, demanding a complete iron panel is essential to uncovering hidden depletion before it spirals out of control.
