Blood tests for iron. Yes, most definitely. It is time to see your physician for iron studies, hemoglobin electrophoresis, if indicated, B12 and folate (folic acid) levels, etc. You may need referral to a hematologist in the future if your anemia continues, depending on how anemic you are, cause, and symptoms.
Anemia. Anemia is diagnosed by a low hemogobin/hematocrit and other factors depending on the type of anemia. If you have iron (Fe) deficiency anemia, your Fe level is low and TIBC is elevated. Symptoms are paleness, fatigue, lightheadedness. You should get these studies repeated after taking Fe for at least 3 months.
