The placenta starts forming human chorionic gonadotropin, which is also known as the pregnancy hormone. This process starts when a fertilized egg appends with the uterus lining. This hormone grows manifold during early pregnancy and is the initiator of many early pregnancy symptoms. Blood pregnancy tests look for the presence of this hormone in a woman’s bloodstream.
Types of Blood Pregnancy Tests
