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/>
