HCG, a protein secreted by human placental trophoblast cells, is elevated during pregnancy. So checking your urine for HCG can tell if you're pregnant. Drug stores sell early pregnancy test strips and to the hospital to check whether there is HCG in the urine, HCG high is pregnant. This is used for qualitative (i.e. positive or negative) purposes.
The increase of human chorionic gonadotropin is associated with pregnancy, but it cannot be determined as intrauterine pregnancy. Suggest you do pelvic cavity B to examine to the hospital.
Human chorionic gonadotropin (HCG) is a glycoprotein secreted by the trophoblastic cells of the placenta. Human chorionic gonadotropin (HCG), synthesized by syncytiotrophoblast cells. The subunits of glycoprotein hormone with molecular weight of 36700 are similar to FSH(follicle-stimulating hormone), LH(luteinizing hormone) and TSH(thyroid-stimulating hormone) secreted by pituitary gland, so they can cross-react with each other. The subunits are not similar in structure. The structure of -HCG is similar to that of -LH, but the last 24 extended amino acids are not present in -LH.
Complete human chorionic gonadotropins are produced entirely by the syncytiotrophoblast of the placental chorionic membrane. Human chorionic gonadotropin is produced by transitional cells and cells of trophoblastic layer. Human chorionic gonadotropin secretion begins 10-14 days after conception.
Patients with hydatidiform mole, malignant hydatidiform mole, chorionic epithelial carcinoma and testicular teratoma have significantly increased urinary HCG, up to 100,000 to millions IU/L, and can be diagnosed by dilution test, such as positive urine at 1:500 dilution before 12 weeks of gestation, positive urine at 1:250 dilution after 12 weeks of gestation, which is valuable for the diagnosis of hydatidiform mole. Positive urine dilution of 1:100 ~ 1:500 is also of diagnostic value for choriocarcinoma. For example, increased URINE HCG in men should be considered for testicular tumors such as seminoma, malformation and ectopic HCG tumor.
According to the article for human chorionic gonadotropin high analysis shows that in most cases, when women for human chorionic gonadotropin detection, if human chorionic gonadotropin is on the high side, shows that the subjects have been pregnant more, besides, it is possible that hydatidiform mole and malignant mole.
