Iron, Total

Iron is a vital nutrient that, amongst other functions, is essential to produce healthy red blood cells (RBCs) and is a critical part of hemoglobin. The total Iron blood test (also known as serum Iron or Serum Fe test) is used to identify if you have too much or too little iron in your body. This test is useful in the early diagnosis of iron deficiency (anemia) and hemochromatosis. Doctors usually order this test if patients have low iron/high iron symptoms such as dizziness, weakness, pale skin, fast heartbeat, stomach pain, lack of energy, and joint pain.
