HCG levels, the hormone found in pregnancy tests, can vary widely. Here’s a chart of what's normal by pregnancy week — and what each level means.
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 (...
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...

dBiochemical pregnancy was defined as serum β-human chorionic gonadotropin (hCG) level more than 30 IU/L 14 days after ET. eMiscarriage was defined as pregnancy loss before the 28th week of gestation; prespecified early and late miscarriages are defined in the Methods section. Table 1. Baselin...
The aim of this study was to examine the distribution of human chorionic gonadotropin (hCG) in the human placenta of normotensive and preeclamptic pregnancies and to determine by computer image analysis, whether differences in hCG immunoreactivity occurred in preeclamptic as apposed to normotensive ...
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. ...

Patient 1 is a girl aged 10 with ambiguous genitalia, XY karyotype, inguinal testes and no pregnantriol and testosterone response to HCG. LHRH stimulated LH was low and remained low 1 week and 6months after bilateral castration while FSH in- creased to very high levels as seen in agonadal...
The American Pregnancy Association says that all pregnant women should be offered an AFP test sometime between the 15th and 20th week of pregnancy. AFP is typically part of the triple screen or quad screen test (along with human chorionic gonadotropin or HCG, estriol, and inhibin A) used in...
