Microcytic anemia is the formation of red blood cells to become small as a result of poor hemoglobinization characterized by a Mean Corpucular Volume (MCV) < 80fl. The purpose of this study was to determine the microscopic analysis of peripheral blood smears in pregnant women with Microcytic Anemia. The population in this sample is pregnant women with anemia as many as 112 pregnant women. The samples in this study were 70 third trimester pregnant women with microcytic anemia. There were five microscopic analyzes of peripheral blood smears which revealed microcytic anemia. And the one with the greatest value was hypochromic microcytic anemia, suspected as the cause of Fe dd deficiency/accompanied by leukocytosis with signs of infection in 50 pregnant women. Among them were 37 (82.2%) pregnant women with mild anemia, there were 13 (59.1%) pregnant women with moderate anemia, 3 (100%) pregnant women with severe anemia. Examination of the peripheral blood smear can only show the results of the cause of microcytic anemia in the direction of suspicion, so other investigations are needed to determine the cause of anemia in pregnant women.
