Pregnancy is one of the most common reasons for a late or missed period. When pregnancy occurs, the body produces human chorionic gonadotropin (hCG). This hormone prevents further ovulation and helps maintain the uterine lining so the fetus can grow. ...
The use of extensive quality controls ensures that good precision is maintained both within and between assays. The range of plasma concentrations of alphafetoprotein in the second half of pregnancy has been established in 100 normal subjects. The levels rise progressively to reach a peak at 32 ...
In early pregnancy, beta human chorionic gonadotropin (βhCG) secreted by syncytiotrophoblasts maintains the corpus luteum, which allows it to continue secreting progesterone until the placenta takes over its function at 7 to 9 weeks of gestation. Progesterone causes secretory changes in the ...
Maternal serum human chorionic gonadotropin (hCG) concentration was slightly elevated in Down syndrome pregnancies, with a median of 1.03 MoM. Both differences were not significant applying matched rank analysis (p=0.50 for TSH and p=0.43 for hCG). The association between TSH and hCG in ...
