beta-hCG
Pronunciation: /ˈbeɪtə ˌeɪtʃsiːˈdʒiː/
Blood test measuring the beta subunit of human chorionic gonadotropin to confirm pregnancy.
Full Definition
A quantitative blood test that measures the beta subunit of human chorionic gonadotropin, the hormone produced by the developing placenta after implantation. Beta-hCG levels are used to confirm pregnancy following embryo transfer and to monitor early pregnancy progress. Rising levels that double approximately every 48-72 hours indicate normal early pregnancy development, while slow-rising or declining levels may suggest pregnancy complications.
Usage
Usage note: The 'beta' designation distinguishes this from the less specific total hCG measurement.
