Maternal 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 was only apparent ...

Evolution of α fetoprotein serum levels throughout life in humans and rats, and during pregnancy in the rat Hemihysterectomy led to a reduction of AFP level that was grossly proportional to the number of remaining fetuses. The stable level of AFP that persists ... R Masseyeff,J Gilli,B Kre...
AFP testing during pregnancy is recommended as an effective way to determine those women potentially at risk of carrying a fetus affected with an open NTD. Used in conjunction with other confirmatory procedures such as ultrasonography or amniography measurement of AFP serves as an important tool in...
Methods: The concen-tration of AFP in amniotic fluid sample from 25,038 second trimester pregnancy women was de-tected by using enzyme linked immunosorbent assay. The outcomes were recorded. Results: The upper limit of reference range and 2.5 MoM of the AFP in different gestational weeks are ...
Abnormal levels are indicative of various pregnancy problems. Deviations of 2.5 multiples of the median or greater above the normal range can indicate various neural tube disorders. On the other hand, levels lower than 70% of the normal range can indicate chromosomal anomalies such as Down and ...
The percentage of Con A non-reactive AFP was significantly lower in the presence of open neural tube defects (< 3.9%, n = 13) compared with that in normal pregnancy (range 6.4–25.2%, n = 25). In this retrospective analysis, 2 pregnancies affected by open neural tube defect escaped ...
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
Logistic regression analysis adjusted for age and weeks of pregnancy at data collection was performed to estimate odds ratios (OR), 95% confidence intervals (95% CI) and p-values separately for each potential predictor. A multiple regression model was used to assess the impact of all promising ...
when the potential is within the range of 0–0.6 V. Thus, the optimal potential of 0.4 V was determined to achieve the detection of AFP. Finally, the different synthesis temperatures of crystalline flake-like ZnIn2S4could influence the photocurrent intensity of the photoelectrode. As shown inFi...
