Beta HCG (Human Chorionic Gonadotropin) is a sensitive test to detect pregnancy.
It can detect pregnancy as early as 10 days after fertilization. Upon conception woman's body starts produces pregnancy hormones called the human chorionic Gonadotropin, commonly referred to as HCG. HCG production begins approximately 8-10 days after conception when the embryo starts implanting to the uterine wall. As the embryo grows the level of HcG rises and generally doubles every 2 to 3 days. The dramatic decrease indicates miscarriage. It is usually done with early morning urine sample. A positive indicates that the individual is pregnant. It can also be detected in the blood.
