Raised 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...
متن کاملSerum human chorionic gonadotrophin levels in early pregnancy.
Serum hCG reference intervals for various gestational periods in normal pregnancies were determined using three commercial assays--two standardized against the WHO 2nd IS (Amersham Amerlex-M beta HCG RIA (AMX) and Abbott beta-HCG 15/15 (ABB] and one standardized against the WHO 1 IRP (Hybritech Tandem -E HCG (HYB]. Serial samples from patients with accurately determined gestational periods were...
متن کاملEffect of gonadotrophin-releasing hormone aned human chorionic gonadotrophin on the response of the ewe to pregnant mare serum gonadotrophin.
An experiment was conducted to determine whether gonadotrophin-releasing hormone (Gn-RH) or HCG would reduce the proportion of unruptured follicles in the Galway ewe following a high superovulating dose of PMSG given in conjunction with a progestagen to synchronize oestrus. Forty-four Galway ewes aged 1\m=1/2\to 5 years (average wt 64\m=.\7kg) were treated with intravaginal pessaries impregnate...
متن کاملUrinary 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 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...
