Amniotic fluid human chorionic gonadotropin in late pregnancy: elevated levels in toxemia with intrauterine growth retardation. 1983

M Heikinheimo, and M Seppälä

Amniotic fluid human chorionic gonadotropin (hCG) was studied by radioimmunoassay in 88 normal pregnancies and in 48 pregnancies with toxemia either with or without intrauterine growth retardation, between 34 and 41 weeks. In normal pregnancy, no significant change in the hCG level was observed from 34 to 41 weeks, with the logarithmic mean value being 522 mU/ml. The hCG levels in amniotic fluid were markedly elevated in toxemia (logarithmic mean 1,079 mU/ml), especially when associated with intrauterine growth retardation (logarithmic mean 2,056 mU/ml). Since in intrauterine growth retardation without maternal disease the hCG levels were normal (logarithmic mean 657 mU/ml), toxemia itself may be the factor that causes elevated levels of hCG in amniotic fluid.

D011225	Pre-Eclampsia	A complication of PREGNANCY, characterized by a complex of symptoms including maternal HYPERTENSION and PROTEINURIA with or without pathological EDEMA. Symptoms may range between mild and severe. Pre-eclampsia usually occurs after the 20th week of gestation, but may develop before this time in the presence of trophoblastic disease.

D011863	Radioimmunoassay	Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation.

D006063	Chorionic Gonadotropin	A gonadotropic glycoprotein hormone produced primarily by the PLACENTA. Similar to the pituitary LUTEINIZING HORMONE in structure and function, chorionic gonadotropin is involved in maintaining the CORPUS LUTEUM during pregnancy. CG consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is virtually identical to the alpha subunits of the three pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity (CHORIONIC GONADOTROPIN, BETA SUBUNIT, HUMAN).

D000653	Amniotic Fluid	A clear, yellowish liquid that envelopes the FETUS inside the sac of AMNION. In the first trimester, it is likely a transudate of maternal or fetal plasma. In the second trimester, amniotic fluid derives primarily from fetal lung and kidney. Cells or substances in this fluid can be removed for prenatal diagnostic tests (AMNIOCENTESIS).
