Beta-hCG (β-hCG) is a test that measures the amount of human chorionic gonadotropin (hCG) in the blood. This hormone is produced as soon as 10 days after conception. In healthy pregnancies, levels of hCG increase rapidly in early pregnancy. An above-normal level can confirm pregnancy. Serial beta-hCG tests done over time can show if hCG levels are increasing, which is a sign that a pregnancy is proceeding normally.
