Urinary chorionic gonadotrophin determination.
Successful laboratory tests for early pregnancy utilize the endogenous production and excretion of chorionic gonadotrophin (CG). There is wide variation in sensitivity and specificity of various biological and commercially available immunochemical methods for determining urinary CC levels. Normal values for immunochemically reactive CC during the first trimester of pregnancy are given. Serial d...
متن کاملAnalysis of chorionic gonadotrophin secreted by cultured human blastocysts.
Embryos produced in an in-vitro fertilization (IVF) programme, but which were unsuitable for transfer to patients because they originated from one (1PN) or three pronuclear (3PN) oocytes or because they originated from two pronuclear (2PN) oocytes but cleaved normally, were maintained in tissue culture. The embryos that progressed to blastocytes were cultured to day 14 of development in order t...
متن کاملElevated Human Chorionic Gonadotrophin Due to Pancreatic Cancer
Preoperative pregnancy testing is common practice among anesthesiologists. Little is re-ported in anesthesia literature on causes other than pregnancy for elevated human chorionic go-nadotrophin (hCG) levels. Among these causes is hCG secretion by tumors. This is a report of a female with pancreatic cancer that presented for a Whipple procedure, who on routine pregnancy testing was found to hav...
متن کاملHuman chorionic gonadotrophin as an indicator of persistent ges-tational trophoblastic neoplasia
Background : Gestational trophoblastic neoplasia (GTN) disease is excessive and inappropriate proliferation of trophoblast after termination of the pregnancy. Many attempts have been made to improve follow-up procedures, but no studies have evaluated Human Chorionic Gonadotrophin (HCG) as a post treatment indicator. Thus we aimed to know β-HCG variability in post treatment pregnancies. Meth...
متن کاملRaised serum human chorionic gonadotrophin concentrations in hyperemesis gravidarum.
Serum human chorionic gonadotrophin (HCG) concentrations were determined by radioimmunoassay with an antiserum specific to HCG beta-subunit in 42 patients with hyperemesis gravidarum and 115 women with normal pregnancies. Mean concentrations (+/- SE of mean) were higher in the women with hyperemesis gravidarum at 7-8 weeks (40.8 +/- 5.2 IU/ml v 22.1 +/- 1.4 IU/ml; P less than 0.001), 9-11 weeks...
