Analysis of beta HCG or HCG to confirm pregnancy

Measuring the amount of human chorionic gonadotropin (HCG), a hormone produced by the developing embryo, by simply drawing blood, indicates whether or not there is a pregnancy.

Human Chorionic Gonadotropin (hCG)

The hormone HCG is also known as “The Pregnancy Hormone”, Human Chorionic Gonadotropin, begins to secrete at the moment of conception and is the hormone that all pregnancy tests detect. If HCG is present in your urine, you are surely pregnant. Its mission is to produce progesterone, the hormone that stimulates the thickening of the uterus preparing it for the implantation of the embryo and that stimulates the development of the mammary glands in the production of milk. This is why the human chorionic gonadotropin hormone (HCG) is produced only in pregnancy. Initially, the developing embryo produces the hormone, while later, when the placenta has already formed, a part of this organ produces HCG. Nausea and vomiting from the first months of pregnancy are related to its presence.

The levels of the hormone HCG or HCG in the blood and urine of the pregnant woman increase dramatically during the first trimester of pregnancy. Specifically, nausea and vomiting from the first months of pregnancy are related to its presence. The hormone HCG is the cause of increased sleep in pregnancy, tiredness, irritability and mood swings during pregnancy.

How the Hormone “Human Chorionic Gonadotropin (hCG)” is detected

The human chorionic gonadotropin hormone is detected with the pregnancy test, although there are also other methods that confirm the existence of a pregnancy. Even, to check the correct development of the pregnancy in the first three or four weeks, the gynaecologist can prescribe to the future mother the dosage of beta-HCG, that is, the measurement of the concentration in the blood of chorionic gonadotropin human, which must be repeated two or more times, with two days of the distance between sample and sample. If the pregnancy develops normally, the concentration doubles in 48 hours.

In other cases, after performing an assisted fertilization treatment, the gynaecologist also usually requests an analysis of the HCG or HCG hormone, in order to check the result of the intervention before the possible pregnancy is visible by ultrasound.

hCG Levels

Normally, a figure of less than 4 mIU / mL indicates the absence of pregnancy. Next, we show you the normal values ​​of the concentration of HCG or HCG hormone in pregnancy :
3-4 weeks: 9-130 mIU / mL

  • 4-5 weeks: 75-2600 mIU / mL
  • 5-6 weeks: 850-20800 mIU / mL
  • 6-7 weeks: 400-100200 mIU / mL

Keep in mind that these values ​​serve to control fetal development, but the week of pregnancy must be confirmed through the first ultrasound.
