PregnancyFirst trimesterMaternal serum alphafetoprotein was assayed in 436 women presenting for termination of pregnancy at 6 to 12 weeks. The normal range for each week is presented. There was a progressive rise of AFP levels from week 7 onwards, but a clear separation from non-pregnant values...
2. For Prenatal Testing - Establish a range of normal values for the new assay based on normal serum, plasma, and amniotic fluids from pregnant women with confirmed gestational age. NAME ARCHITECT AFP (alpha-fetoprotein) INTENDED USE The ARCHITECT AFP assay is a Chemiluminescent Microparticle ...

For example, a 35-year-old woman has a risk of a Down syndrome term pregnancy of about 1:380, the risk is 1:120 if the AFP level is 0.40 multiples of the normal median (MoM) and 1:1800 if it is 2.50 MoM. Software providing computer assisted test interpretation has been produced to...
Through safe and cost efficient immunoassays, alpha-fetoprotein is measured in maternal serum. When variables such as gestational age, maternal age, maternal weight, race, diabetes, and multiple pregnancy are taken into account, the calibrated range of normal maternal serum alpha-fetoprotein (MSAFP) ...
Theoretical ranges of normal AFP variation are presented. The extreme range of AFP in serum samples from 236 nonpregnant blood donors varied fron .2-18.3 mcg/liter. Variability of AFP in maternal serum samples increased considerably with gestational progress. A specific low cut-off could not be ...
We suggest that women with elevated serum AFP or hCG should receive standard pregnancy care once they have reached 37 weeks of gestation if fetal growth is in the normal range.SabrinaTancrèdeEmmanuelBujoldYvesGiguèreMarie-HélèneRenaldJoel
