What Are the Causes of HCG in Urine?
Human chorionic gonadotropin, also known as HCG, is a hormone usually associated with pregnancy. A urine test can detect the presence of HCG, and a blood test measures the amount of HCG in the blood. This hormone is generated by the same cells that will form a placenta to nurture the fetus after it has been implanted as a fertilized egg. In the majority of normal pregnancies, the levels of HCG double every 48 to 72 hours. There are, however, other possible causes for HCG in the urine.
