Beta human chorionic gonadotropin (HCG): Female, premenopausal nonpregnant: ˂1.0 U/L; female, postmenopausal: ˂7.0 U/L; male: ˂1.4 U/L CA19.9: 0–37 U/mL Carcinoembryonic antigen (CEA): ˂2.5 ng/mL Prostatic acid phosphatase (PAP): 0-3 U/dL Prostate-specific antigen (...
Our project of identifying HCG producing cells, together with monthly observations of the morphologic changes in normal human chorionic villi, led to the following conclusions. Until about the 10th wk of pregnancy, the epithelium of the chorionic villi consists of two distinct layers: syncytium and...
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. What Is Amenorrhea? Amenorrheais when you st...
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...
