What is the definition or description of: urine hcg?

Pregnancy test: Beta-hcg is the hormone that rises exponentially in a woman's bloodstream when she is pregnant. Pregnancy can be diagnosed by either detecting HCG in the blood or in the urine. A positive HCG test in either place means the woman is pregnant in most cases.

HCG: Hcg= human chorionic gonadotropin, a hormone produced during pregnancy that is made by the developing placenta after conception, and later by another placental component (syncytiotrophoblast).
