The Beta Human Chorionic Gonadotropin (Beta hCG) test is a blood test used to detect the presence and measure the levels of the Beta hCG hormone in the blood. This hormone is produced by the placenta after a fertilized egg has implanted in the uterus, and its presence in the blood can indicate pregnancy. The Beta hCG test is commonly used to confirm and monitor pregnancy, as well as to detect abnormal pregnancies, such as ectopic pregnancies or molar pregnancies. It can also be used as a tumor marker in some types of cancers, such as testicular or ovarian cancer, as these tumors can produce Beta hCG. The test involves the collection of a small blood sample from the patient, which is then sent to a laboratory for analysis. Results are typically available within a few days.
