+Notably, the GBD does not have any estimates related to ferritin exposure or ferritin screening. However, the GBD assigns specific causes to all cases of anemia. Some of these causes of anemia are considered "iron 
 responsive," indicating that they are iron deficiency anemia. An example of an iron deficiency anemia is anemia caused by maternal hemorrhage (caused by blood loss, decreasing systemic levels 
 of both hemoglobin and iron). An example of a non-iron responsive anemia is sickle cell trait (low hemoglobin is due to a defect in hemoglobin protein rather than low iron levels). Notably, it 
 is possible for non-iron-responsive anemias to also have low iron levels. See the :ref:`anemia impairment document <2019_anemia_impairment>` for a list of iron responsive and non iron responsive
