Background The prognostic role of human chorionic gonadotropin (hCG) and lactate dehydrogenase (LDH) serum levels in seminoma patients remains uncertain. This observational study evaluates the prognostic impact of tumour marker levels, and other clinicopathological findings, in hCG-positive seminoma ...
Both human chorionic gonadotropin (HCG) and human placental lactogen (HPL) strongly stain the syncytiotrophoblast cells of choriocarcinomas and those intermixed with other germ cell tumors (see Fig. 18.12D).17,68 The mononucleated trophoblastic cells are generally weakly positive or negative for HCG...
The adult and fetal rat brain contains human chorionic gonadotropin/luteinizing hormone (hCG/LH) receptors, that are functional in mediating the neurotropic, neuroendocrine and behavioral actions of gonadotropins. We hypothesized that the spinal cord also contains these receptors. We have now demonstrate...
In the testicular germ cell tumors,the measurement of urine hCG-β-core fragment is useful for differential diagnosis in cases of low level-positive serum hCG-β without clinical evidence of disease. 展开 关键词: Seminoma Human chorionic gonadotropin β False-positive ...
It is widely known that luteinising hormone (LH) and human chorionic gonadotrophin (hCG) are integral in the female reproductive lifecycle. Due to the common binding site and similarity in molecular structure, they were previously thought to have overlap
Human chorionic gonadotropin (hCG) is a glycoprotein hormone comprising 2 subunits, alpha and beta joined non covalently. While similar in structure to luteinizing hormone (LH), hCG exists in multiple hormonal and non-endocrine agents, rather than as a s
False-negative reports are frequently obtained during late pregnancy when the secretion of chorionic gonadotropin normally decreases. The possibility not only of false-negative but also of false-positive tests makes the tests, at best, probable rather than absolute evidence of the presence or absence ...

Where both the indirect peroxidase-labeled and the fluorescein-labeled antibody tests are positive, human chorionic gonadotropin is present in the cells tested. Where both indirect tests are negative or where one test is positive and the other is negative, human chorionic gonadotropin is not present...
