Since NT screening must be done between weeks 11 and 14, an accurate date of conception is important for an accurate result. (A recent study found that NT scans done during week 11 were the most accurate of all because the fold is most translucent then.)
11周-14周前都可以,最近研究还发现11周时做的最准确。我订了11+4去做,抽血同一天。 |
