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 کاملAn Immunochemical Test for Chorionic Gonadotrophin.
An immunochemical procedure for routine laboratory diagnosis of pregnancy utilizing adsorption of human chorionic gonadotrophin onto kaolin and the Ortho pregnancy test reagents is described. The method is suitable for quantitative assay of urinary human chorionic gonadotrophin and can be adapted for use with serum. It was found to compare favourably with the reliability of Galli-Mainini toad t...
متن کاملChorionic Gonadotrophin, ACTH, and the Adrenal-Hyaluronidase Relationship *
It has been shown that either adrenocorticotrophic hormone (ACTH) or the 11-oxygenated adrenal cortical steroids inhibit the hyaluronidaseenhanced spreading phenomenon in the rabbit and in the mouse.q 8 In view of the favorable influence of pregnancy on certain of the collagen diseases, it was of interest to determine whether chorionic gonadotrophin had any influence on this phenomenon. This wa...
متن کاملUltrastructural Modifications of Human Endometrium during the Window of Implantation
The endometrium is a highly dynamic tissue empowered with the capacity to undergo cyclic dramatic changes in response to ovarian steroid hormones, ultimately aiming to create a window of receptivity for blastocyst implantation. Intensive research has been performed to understand and establish morphological and molecular correlates of embryo implantation. However, it still remains a biological m...
متن کاملThe association of maternal factors with delayed implantation and the initial rise of urinary human chorionic gonadotrophin.
BACKGROUND Late implantation and the pattern of early rise in hCG have been associated with early pregnancy loss. We explored factors that might be predictive of these markers of poor embryonic health in spontaneously conceived pregnancies. METHODS Participants in the North Carolina Early Pregnancy Study collected daily first-morning urine specimens while attempting to conceive. Samples were as...
