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 post-conception and an above-normal level can confirm pregnancy.
A quantitative test (or beta) measures the amount of hCG actually present in the blood. Guideline to hCG levels in weeks during pregnancy * These numbers are just a guideline – every woman’s level of hCG can rise differently.
Let’s take a look at the potential hCG levels in weeks from your last monthly period. 3 weeks: 5 – 50 mIU/mL. 4 weeks: 5 – 426 mIU/mL. 5 weeks: 18 – 7,340 mIU/mL. 6 weeks: 1,080 – 56,500 mIU/mL. 7 to 8 weeks: 7,650 – 229,000 mIU/mL. 9 to 12 weeks: 25,700 – 288,000 mIU/mL. 13 to 16 weeks: 13,300 – ...

HCG is a hormone produced in the body during pregnancy. Other HCG tests include: HCG urine test; HCG blood test -- qualitative; Alternative Names. Serial beta HCG; Repeat quantitative beta HCG; Human chorionic gonadotropin blood test - quantitative; Beta-HCG blood test - quantitative; Pregnancy test - blood - quantitative. How the Test is Performed
A positive beta human chorionic gonadotropin (hCG) level usually means that you are pregnant. Pregnancy tests detect the hCG hormone in the blood and urine. The beta hCG levels are also measured using a test known as quantitative hCG testing. This test measures the quantity of hCG in your urine in terms of mIU/mL or IU/L.
hCG-beta is a hormone produced by the rapidly dividing placental cells of your embryo. Its main function is to stimulate your corpus luteum, a structure created when your ovary releases an egg, to continue to produce estrogen and progesterone. These hormones are very important for maintaining the endometrial lining.
A bhCG test refers to a Beta Human Chorionic Gonadotropin test. While an hCG test is done through a urine sample, the bhCG test is performed on your blood sample. The bhCG test checks for a confirmed pregnancy and results will usually show as positive when you miss your first period.
However, the beta form or the beta hCG is the free hCG that is present in humans. This is the key difference between beta hCG and hCG hormone. However, the accuracy in detecting the two types vary. Beta hCG is more accurate in detection than total hCG.
