My blood work came back high for "ERYTHROCYTE DISTRIBUTION WIDTH" or Red blood cell distribution width. the range is supposed to be between 11.5-14.5 and mine is 17.5. Should I be concerned?

Red Cell Distribution Width (RDW): A measure of the variation in size between red blood cells. Useful in evaluating the cause of, and therapy for, anemia. Increased values may indicate a number of things including vitamin B12, folic acid, or iron deficiency.

My Hematocrit and Hemoglobin are also low. So all 3 seem to point to me being anemic. Will taking B12 resolve this?

Hematocrit: A measure of the percentage of red cells in the blood. Low levels indicate an anemic condition.High levels may indicate a number of things including dehydration, increased red cell breakdown in the spleen, cardiovascular disease, or respiratory disease. Anabolic steroids may also increase hematocrit.

Hemoglobin: A constituent of red blood cells, and the main carrier of oxygen and carbon dioxide in the blood. Levels may be suppressed with a number of conditions including malnutrition, malabsorption, and anemia. High levels may indicate many things including dehydration, cardiovascular disease, or respiratory disease. Anabolic steroids may also increase hemoglobin levels.
