ßhCG是一种有效的妊娠生物标志物
ßhCG是胎盘在妊娠期分泌的一种激素。它可诱导产生雌激素和孕酮,同时抑制母体免疫系统,维持胎儿生长[4, 5]。
大部分妊娠检查都会测定ßhCG水平,在妊娠期的前几周, ßhCG可在血液和尿液样本中检测到,但通常在血液中浓度更高。怀孕后约11天,妊娠血液检查即能检测到ßhCG,比标准尿液检查可提前数天[6]。大部分妊娠检查都会测定ßhCG水平,在妊娠期的前几周, ßhCG可在血液和尿液样本中检测到,但通常在血液中浓度更高。怀孕后约11天,妊娠血液检查即能检测到ßhCG,比标准尿液检查可提前数天[6]。
妊娠血液检查也比典型的尿液试纸检查更加灵敏,可提供定量结果以辅助临床评估[3]。
