Just like high Beta HCG values, low beta HCG concentration can have many reasons. If the Beta HCG value are inbetween 0-5, that means pregnancy did not occur. This calculation gives us an estimation for the reasons stating above.īased on your last menstruation date, your estimated pregnancy week and Beta HCG values are given below.ħ-12 week prepgnant: 7.650-290.000 mIU/ml,ġ3-16 week prepgnant: 13.300-250.000 mIU/ml,ġ7-24 week prepgnant: 4.000-165.000 mIU/ml. Following up HCG decrease is important for molar and ectopic pregnancies.īeta HCG calculation, According to the beta hCG value, it is estimated in which week of pregnancy you are. On the pregnancy ends with 7 to 60 days HCG values are dropped down to 0. Values in between 6 – 24 mlU/ml is defined as grey area, and test is repeated within few days. When blood tests are done, if the HCG value is below 5 mlu/ml results is determined as negative, in other word it means negative results, if the value is above 25 mlU/ml result is positive. On the other hand, blood tests are very sensitive. Therefore, in these tests, even if the person is pregnant, they may get negative results, especially at a very early stage. Most pregnancy test kits in the pharmacy, cannot detect hyperglycolyzed forms of hCG. In most urine tests, the hCG level must be greater than 20 mIU / mL for test to be positive. Diagnosing Pregnancy via Beta HCGīeta HCG (serum tests), which are measured by blood for pregnancy diagnosis, are much more sensitive than urine tests. Having increased HCG values outside of pregnancy may point out to other medical issues these can be congenital anomalous such as down syndrome, testicle or ovarian cancer or liver tumours. To eliminate these reasons, test needs to be reconducted within 48 to 72 hours. Increased value of H CG can have many reason. Therefore, HCG value alone is not enough to detect healthy pregnancy.
Once the HCG reaches to 1000-2000 mlU/ml in body, with transvaginal ultrasound pouch can be observed.Īlong with this, compared to other hormones, HCG shows the biggest difference in concentration for every pregnant women. On health pregnancy, HCG values doubles itself in every 72 hours. Untill the 8th week, serum (blood) HCG concentration increases rapidly. Half the pregnant women, has about 25 mlU/ml concentration. This period, is equal to 3 to 4th week after last menstruation.
5mlU/ml) after 8th to 11th day of insemination. It reaches to sufficient concentration (app. When HCG Values Increase?ĭuring normal pregnancy HCG producticon starts when plancenta adherences to the uterus. Therefore, hormone can be observed either in blood and urine of pregnant women.
– Blocks phagocytosises from attacking the cells that are feeding the embryo.īeta HCG hormone is produced in the liver of the mother and 20% of it is disposed by kidney. – Helps increasing the veins in the uterus – Helps, expanding uterus, as the embryo develops Other then this, recent studies shown Beta SHCG has multiple functions. In other word, Beta HCG hormone communicates between embryo and ovaries, and helps production of hormone which is needed for pregnancy. Progesterone which is produced by corpus luteum, is needed during pregnancy.
The function of this hormone is communicates with structure called corpus luteum within the ovaries. Once the embryo adherences to the uterus wall, cells called syncytiotrophoblast produces, hCG hormone. HCG (Human chorionic gonadotropin), is an hormone that is released during pregnancy by plasenta.
