hCG Level in Early Pregnancy

    What is hCG?

    hCG is the abbreviation for "Human Chorionic Gonadotropin," also known as the "pregnancy hormone." This hormone is produced by the placenta as soon as implantation happens, about one week after fertilization and ovulation. hCG levels continue to rise after implantation until about 10-12 weeks gestation, at which point the hCG level will stabilize or drop. Pregnancy tests detect the amount of hCG in the blood or urine, and a pregnancy test becomes positive when there are sufficient levels of hCG. Blood hCG testing is much more sensitive than urine hCG testing, therefore a blood hCG test can detect pregnancy several days before a urine pregnancy test.

    How soon can I detect a pregnancy? 

    Among the most common and important questions asked by women is: "How soon can I detect my pregnancy?" Most pregnancy tests and symptoms depend on high enough hCG levels — the higher the hCG level, the more symptoms you will have.

    A pregnancy is typically detected by a missed period and implantation bleeding, as well as through typical pregnancy symptoms and a positive pregnancy test. You can help detect your pregnancy now by doing our online pregnancy test (OPT), and can calculate your hCG levels with the hCG Calculator.

    What does my hCG level mean?

    • hCG under 5 mIU/ml: Negative. Not pregnant
    • hCG between 5-25 mIU/ml: "Equivocal." Possible pregnancy but not definitive. Repeat test in a couple of days.
    • hCG over 25 mIU/ml: You are pregnant!

    In most normal pregnancies with hCG levels below 1,200 mIU/ml, the hCG usually doubles every 48-72 hours and increased by at least 60% every two days.

    • hCG under 5 mIU/ml: Negative. Not pregnant
    • hCG between 5-25 mIU/ml: "Equivocal". Maybe pregnant maybe not. Repeat test in a couple of days
    • hCG over 25 mIU/ml: You are pregnant!

    A positive pregnancy test means that there is a sufficient amount of hCG in your body.The presence of normal hCG levels usually indicates that you are pregnant. - See more at: http://www.babymed.com/pregnancy-tests/hcg-levels-and-pregnancy-testing#...

    What does it mean if the hCG is "slow rising"?

    Many women wonder whether they have a normal hCG level or not and in fact there is a wide range of normal hCG (pregnancy hormone) levels in early pregnancy. Many women wonder whether they have a normal hCG level or not.

    • An hCG level below 5 mIU/ml is considered "not pregnant."
    • An hCG level above 25 mIU/ml is considered "pregnant."
    • An hCG level between 5-25 mIU/ml requires a follow-up test to confirm what it could be.
    • At hCG levels in early pregnancy below 1,200 mIU/ml, the hCG usually doubles every 48-72 hours and it should normally increase by at least 60% every two days. 
    • Between 1,200 and 6,000 mIU/ml serum hCG levels in early pregnancy, the hCG usually takes 72-96 hours to double.
    • Above 6,000 mIU/ml, the hCG often takes over four or more days to double.
    • In general, when the HCG level reached 7200 mIU/ml, a yolk sac should be seen
    • At an HCG level greater than 12,000 mIU/ml there should be a  visible embryo with a heartbeat, though it could take up to an hCG level of 22,000 mIU/ml to first see the fetal heart beat.
    • After 9-10 weeks of the pregnancy hCG levels normally decrease.

    It makes little sense to follow the hCG level in early pregnancy above 6,000 mIU/ml as at this point the increase is normally slower and not related to how well the pregnancy is doing. After two to three months the hCG numbers in early pregnancy will slow even further and eventually hCG levels even decline before reaching a plateau for the duration of the pregnancy.

    There is really no single "normal" hCG level in early pregnancy and there is a very wide range of hCG values as pregnancy progresses.

    If you are interested in finding out if your pregnancy hCG level is progressing normally or not, the most important information is to find out whether your blood hCG level is rising normally or not. See normal blood hCG levels below and more information about hCG HERE.
