초기 정상임신중 임신부 혈청 Alpha-Fetoprotein치에 관한 연구 (II) = A Study on Maternal Serum Alpha-Fetoprotein Levels in Early Normal Pregnancies (II)

다국어 초록 (Multilingual Abstract)

A normal range of maernal serum alpha-fetoprotein(MSAFP) levels was estimated in 940 normal pregnant women between 14 and 22 weeks gestation by enzyme immuonassay, which consisted of 217 in thefirst study from February 1984 to July 1985 and the rest of 723 from August 1985 until February 1990. The upper and lower limits of normal range of MSAFP were calculated for each gestational week using multiples of median (MoM), 2.5, 2.0MoM & 0.8, 0.4, 0.25 MoM, respectively. The weight adjusted MoM can be calculated by dividing an unadjusted MoM by the expected MoM for that maternal weight, using the following formula: Expected MoM=10^(0.24972-0.00471594*Body weight(kg)) A normal range of MSAFP levels should be established through a much larger population of pregnant women and investigation.
