Lab Tests for Iron Deficiency
Iron deficiency is the most common nutritional deficiency worldwide and the leading cause of anemia. It can cause persistent fatigue, weakness, pale skin, brittle nails, restless legs, and difficulty concentrating. Women, vegetarians, and endurance athletes are at highest risk. Lab testing is essential because iron deficiency can exist for months before anemia develops — catching it early through ferritin testing prevents progression. With JustLabs, you can order iron studies online at transparent prices, no doctor visit or insurance required.
