Laboratory approach to investigation of anemia in pregnancy

다국어 초록 (Multilingual Abstract)

Anemia is a global health problem in all age groups. According to World Health Organization (WHO), approximately 40% of pregnant women are anemic. Iron deficiency anemia (IDA) due to nutritional deficiency is the most common cause. The incidence of IDA varies worldwide depending on the socioeconomic status, but it remains the leading cause even in developed countries. Physiologic anemia of pregnancy due to relatively higher expansion of blood volume in comparison with elevated red blood cell mass also occurs frequently. Complete blood count (CBC) in the first trimester is recommended for all pregnant women to screen for anemia. The screening of pregnant women for IDA in absence of anemia is still debatable. If IDA is suspected, ferritin level of <30 ng/ml is diagnostic. Iron supplementation is recommended for all pregnant women to compensate the increased demand.
