Laboratory chemical analysis of capillary blood to determine the ferritin level. Iron is an important trace element primarily required for blood formation in the human body. Iron is also responsible for oxygen transport and storage, largely through the enzyme ferritin. Iron deficiency most commonly arises from poor diet, gastrointestinal bleeding in men and women, and in regular blood donors. In women, iron deficiency often occurs during heavy menstruation and pregnancy. In children and adolescents, cognitive abilities can be negatively affected by iron deficiency. A possible link between ADHD and iron deficiency is also known. An iron deficiency blood test measures your ferritin level to detect a potential iron deficiency.
