Abstract


OBJECTIVE
To determine normal range of amniotic fluid alpha-fetoprotein (AFAFP) in midtrimester singleton Korean pregnant women whose pregnancy and neonatal outcomes were uneventful.
METHODS
AFAFP levels were measured in midtrimester pregnancy during amniocentesis from May 1995 to September 2006 at tertiary referral center. Normal ranges were obtained from 954 singleton pregnancies in which pregnancy and neonatal outcomes were normal.
RESULTS
Median values of AFAFP in midtrimester pregnancy were 15,800 ng/mL, 13,903.9 ng/mL, 11,408.7 ng/mL, 9,690.1 ng/mL, 6,923.4 ng/mL, 6,330.0 ng/mL, 5,295.3 ng/mL, 4,421.2 ng/mL, 3,162.5 ng/mL at 16 week, 17 week, 18 week, 19 week, 20 week, 21 week, 22 week, 23 week, and 24 week.
CONCLUSION
The normal range of AFAFP level in each gestational week in Korean women could be a good reference for prenatal diagnosis of various disorders.
