Definition (NCI) Any examination performed to assess if a female is gravid.
Definition (MSH) Tests to determine whether or not an individual is pregnant.
Definition (CSP) determining whether or not a female is pregnant.
Definition (NCI_NCI-GLOSS) A hormone normally found in the blood and urine during pregnancy. It may also be produced by some tumor cells. An increased level of beta-human chorionic gonadotropin may be a sign of cancer of the testis, uterus, ovary, liver, stomach, pancreas, or lung. Beta-human chorionic gonadotropin may also be produced in response to certain conditions that are not cancer. Beta-human chorionic gonadotropin is being studied in the treatment of Kaposi sarcoma.
Definition (NCI) Choriogonadotropin subunit beta (165 aa, ~18 kDa) is encoded by the human CGB gene. This protein is involved in the regulation of steroid synthesis during pregnancy.
Definition (MSH) The beta subunit of human CHORIONIC GONADOTROPIN. Its structure is similar to the beta subunit of LUTEINIZING HORMONE, except for the additional 30 amino acids at the carboxy end with the associated carbohydrate residues. HCG-beta is used as a diagnostic marker for early detection of pregnancy, spontaneous abortion (ABORTION, SPONTANEOUS); ECTOPIC PREGNANCY; HYDATIDIFORM MOLE; CHORIOCARCINOMA; or DOWN SYNDROME.
