看到很多宝妈因为HCG翻倍不好而各种担心着急,所以特意找来国外医学网站上的信息以供参考。其实HCG只是一个参考指标,并不是一切,好与不好都不能完全说明你家宝宝是否健康正常。有耐心的就看完吧。
In many early pregnancies, the hCG level will double every 31 to 72 hours. As the pregnancy progresses, hCG levels rise and the doubling time increases. (许多的早孕, 和hCG水平每31-72小时会翻倍, 随着怀孕的进程, HCG水平的上升以及翻倍的时间也会增加。 )
"Normal" Doubling Time (“正常”翻倍时间)
hCG levels ( hCG水平)
Doubling Time (翻倍时间)
Under 1200 mIU/ml (1200 以下) 31-72 hours (31-72小时)
Between 1200 to 6000 mIU/ml (1200-6000) 72-96 hours (72-96小时)
Over 6000 mIU/ml (6000 以上) more than 96 hours (大于96小时)
hCG levels rise during the first 6 to 10 weeks of pregnancy then decline slowly during the second and third trimesters. (hCG水平在最初的6-10周会上升,之后会逐渐降低)
•The hCG levels will usually double approximately every 48 hours [ 2 days ] for the first four weeks of pregnancy. (hCG 在最初4周常常每48小时(2天)翻倍一次)
•As pregnancy progresses the doubling time increases. By 6 to 7 weeks gestation beta hCG levels may take as long as 84 hours [ 3½ days ] to double. (随着孕期进程,翻倍时间增加。到6-7周,HCG水平需要84小时(3.5天)才翻倍一次)
•The beta hCG may take more than 48 - 72 hours [ 2 to 3 days ] to double in 15% of normal intrauterine pregnancies.(15%的宫内妊娠HCG的翻倍时间超过48-72小时)
•About 17% of ectopic pregnancies have normal doubling times. (17%的宫外孕有正常的HCG翻倍)
