BIOCHEMICAL METHODS OF PRENATAL SCREENING DIAGNOSTICS

Prenatal diagnostics is a set of measures aimed at detecting pathologies during intrauterine development. One of the least invasive, yet diagnostically significant methods is biochemical screening, which allows expecting parents to receive early information about the risk of giving birth to a child with a pathology and, in extreme cases, about the need to terminate the pregnancy.产前诊断（Prenatal diagnostics）是一类旨在检测胎儿宫内发育病理异常的综合诊疗措施。其中，侵入性最低且兼具重要诊断价值的方法之一为生化筛查（biochemical screening），该手段可为准父母提前获悉胎儿罹患发育异常的出生风险，极端情况下还可提示是否需要终止妊娠。
