What does hCG beta subunit test for?
HCG, Beta subunit level reported in IU/L. Test Indications: Useful for monitoring patients for retained products of conception. Diagnosis of gestational trophoblastic disease (GTD), testicular tumors, ovarian germ cell tumors, teratomas, and, rarely, other human chorionic gonadotroping (hCG)-secreting tumors.
What is hCG beta subunit Qual?
Test Information: Similarly to LH, FSH, and TSH, human chorionic gonadotropin (hCG) is a member of the glycoprotein family and consists of two subunits (α- and β-chains) that are associated to the intact hormone. Measurement of the hCG concentration permits the diagnosis of pregnancy just one week after conception.
What is a positive abnormal pregnancy test?
What Abnormal Results Mean. HCG level should almost double every 48 hours in the beginning of a pregnancy. HCG level that does not rise appropriately may indicate a problem with your pregnancy. Problems related to an abnormal rising HCG level include miscarriage and ectopic (tubal) pregnancy .
Does Beta hCG confirm pregnancy?
Qualitative testing: Also known as the urine pregnancy test, the qualitative beta hCG test is the over-the-counter pregnancy test that only indicates whether you are pregnant. A doctor usually orders a beta hCG blood test to confirm pregnancy after a positive urine pregnancy test.
What is the beta subunit of hCG?
HCG hormone is heterodimeric protein, with an α (alpha) subunit identical to that of luteinizing hormone (LH), follicle-stimulating hormone (FSH), thyroid-stimulating hormone (TSH), and β (beta) subunit that is unique to hCG. Learn when to take pregnancy test? What is the blood tests measure hcg beta subunit levels?
What is the Alpha and beta subunit of FSH?
The alpha subunit is the same one used by other sex/pituitary hormones: FSH, LH, and TSH. The beta subunit, though, is unique to HCG and that’s why pregnancy tests look for the presence of beta-HCG. LH hormone produced in the pituitary gland of males and females of all ages and resemble HCG in its structure. What does β beta subunit means?
How do you test for beta subunit hCG?
Best and accurate methods to test for beta subunit hCG level: B-HCG detected in Blood or urine samples for qualitative measurement of hCG. hCG levels are also a component of the triple test, a screening test for certain fetal chromosomal abnormalities/birth defects.
What is a normal hCG beta level for a man?
The level of human seminal chorionic gonadotropin beta-subunit (hCG beta) was determined by radioimmunoassay (RIA). The mean hCG beta level in 34 normal men was 3.7 +/- 1.6 ng/ml, which was much higher than that in serum.
