As pregnancy progresses the doubling time increases. By 6 to 7 weeks gestation beta hCG levels ...
BACKGROUND:Human chorionic gonadotropin (hCG) is produced by the trophoblast early in pregnancy and peaks at a level of approximately 100,000 IU/liter around the ninth week of gestation. Abnormally high levels are usually noted in association with multiple gestation, molar gestation, and specific ...
It is made up of two subunits, the alpha subunit which is common to other hormones produced by the pituitary gland and the beta subunit which is specific to HCG. As gestation progresses, the levels of this hormone increase. Although there are large variations from one week to the next, ...
The normal level of hCG varies especially in early pregnancy, as it’s produced by the placenta immediately after implantation takes place and rise progressively. Most of the women will wonder if they have a normal hCG or not. Here are some of the hCG levels figures which might be very use...
The hCG levels were analysed as multiple of the median (MoM). Odds ratio (OR) and 95% confidence interval (CI) were used. Risk of bias and the certainty of evidence were assessed using ROBINS-I and GRADE, respectively. Meta-analysis also showed that hCG levels, reported as MoM ≥2/...

Maximal production rates of up to 12 ng/mg tissue/h were seen. It is concluded that human fetal testes bind hCG, and that physiologic levels of hCG stimulate fetal testicular testosterone formation in vitro at this stage of gestation. 展开 ...
Objective:To explore the relationship between β-human chorionic gonadotropin(β-HCG),human placental lactogen(HPL) and multiple pregnancies by measuring β-HCG and HPL in early pregnant women.Methods:The serum levels of β-HCG and HPL in 18 women with multiple pregnancies(including two and three...
Maternal demographic features, the results of first trimester sonography and biochemical parameters of all pregnant women at 11 to 13 + 6 weeks of gestation were collected. NT thickness and the presence/absence of nasal bone were also recorded. Serum levels of β-hCG and PAPP-A were ...
of patients were detected by automatic chemiluminescence analyzer, and the serum hCG levels of the three groups were compared. Results the serum hCG levels of pregnant women, patients with ectopic pregnancy and hydatidiform mole disease increased significantly after 35 days and 10 weeks of gestation ...
