Anemia in pregnancy is a decrease in the total red blood cells (RBCs) or hemoglobin in the blood during pregnancy. Anemia is an extremely common condition in pregnancy world-wide, conferring a number of health risks to mother and child. [ 2 ]
Hematocrit levels that are too high or too low can indicate a blood disorder, dehydration, or other medical conditions. [4] An abnormally low hematocrit may suggest anemia, a decrease in the total amount of red blood cells, while an abnormally high hematocrit is called polycythemia. [5] Both are potentially life-threatening disorders.
The World Health Organization defines low ferritin in adults as below 15 nanograms per milliliter, but in clinical practice, iron deficiency may be diagnosed when ferritin is below 30 nanograms ...
For example, during pregnancy a woman's RBC mass is normal but because of an increase in blood volume the hemoglobin and hematocrit are diluted and thus decreased. Another example would be bleeding where the RBC mass would decrease but the concentrations of hemoglobin and hematocrit initially remains normal until fluids shift from other areas ...

Iron deficiency can also cause shortness of breath, and amplify the symptoms of any chronic condition, such as depression. It can also have an affect on your mood, ability to focus and sleep quality .
It is found that since blood loss attributable to laboratory testing is the primary cause of anemia among preterm infants during the first weeks of life, it would be useful to quantify blood loss attributable to phlebotomy overdraw (ie, blood collected in excess than what is strictly required for the requested lab tests).
