Iron Deficiency Anemia

Iron deficiency anemia (IDA) is an anemia caused by low iron stores in the body; it accounts for approximately half of all anemia cases.   IDA may result from low dietary iron intake, blood loss, increased physiologic demand (eg, periods of rapid growth), or the use of certain medications, among other causes.  Initial testing for IDA typically includes an assessment of hemoglobin (Hb), hematocrit (Hct), and red blood cell (RBC) indices such as mean corpuscular volume (MCV), followed by serum ferritin (SF) if Hb levels are 2 standard deviations below normal for age and sex. Total iron binding capacity (TIBC), transferrin saturation (Tsat), and other tests may also be helpful for diagnosis if anemia of chronic disease/anemia of inflammation (ACD/AI) is a possibility. Treatment for IDA depends on the cause of anemia, but generally begins with oral supplemental iron. Hb, Hct, RBC indices, SF, and other tests may be used to monitor the effectiveness of treatment.
