A beta hCG blood test measures the amount of pregnancy hormone rather than giving a yes/no answer, so it can detect pregnancy earlier and more precisely than a urine test. Clinics use it about nine to fourteen days after transfer. A single value cannot tell you how a pregnancy will progress; the trend across repeat tests is more informative.
Also known as: blood pregnancy test, BHCG, beta test, hCG level
