羊水与胎儿有密切关系,胎儿在母体子宫内,漂浮于羊膜腔储存的羊水中。羊水中的脱屑细胞来自胎儿的皮肤和消化、呼吸、泌尿生殖系统等处。这些细胞具有胎儿的遗传信息。因此,检查羊水及羊水中的脱屑细胞,能够反映胎儿的生理与病理状态。羊水诊断就是通过羊膜穿刺采取羊水进行检查,以判断胎儿成熟程度及诊断某些胎儿疾病的一种方 Amniotic fluid and the fetus are closely related to the fetus in the mother’s uterus, floating in amniotic fluid stored amniotic fluid. Amniotic fluid desquamation cells from the fetus’s skin and digestion, breathing, genitourinary system and so on. These cells have fetal genetic information. Therefore, check the amniotic fluid and amniotic fluid desquamation cells, can reflect the fetus’s physiological and pathological state. Amniotic fluid diagnosis is through amniocentesis to take amniotic fluid to check to determine the degree of fetal maturity and diagnosis of certain fetal diseases, a party
