A total of 123 twin pregnancies were studied, 68 by records analysis only, and 55 by serial haematological assessment in detail. The incidence of low haemoglobin levels is found to be greater than in singleton pregnancy; evidence of iron and folic acid deficiency is common in sternal marrow aspirates but not in peripheral blood films. Routine haematinic prophylaxis in twin pregnancy is not advocated.
共对123例双胎妊娠进行了研究，其中68例仅通过记录分析，55例进行了详细的系列血液学评估。发现低血红蛋白水平的发生率高于单胎妊娠；胸骨骨髓穿刺中常见铁和叶酸缺乏的证据，但外周血涂片未见。不提倡对双胎妊娠进行常规补血预防。
