看到论坛里许多刚怀孕的准麻麻都非常担心HCG 翻倍的问题,我从国外医学网站上摘录了以下信息,并翻译了一下。希望对姐妹们有用。
<br/>
<br/>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。 )
<br/>
<br/>
<br/><br/>"Normal" Doubling Time (“正常”翻倍时间)
<br/>hCG levels ( hCG水平)Doubling Time (翻倍时间)
<br/>Under 1200 mIU/ml (1200 以下)31-72 hours (31-72小时)
<br/>Between 1200 to 6000 mIU/ml (1200-6000)72-96 hours (72-96小时)
<br/>Over 6000 mIU/ml (6000 以上)more than 96 hours (大于96小时)
<br/>
<br/>
<br/>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)
<br/>
<br/>
<br/>
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)
<br/>
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)
<br/>
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)
<br/>
About 17% of ectopic pregnancies have normal doubling times. (17%的宫外孕有正常的HCG翻倍)
