With the development of society and the spread of the concept of equality, hospitals have set limits on the identification of the sex of the fetus. Therefore, if you want to know the sex of the baby in your belly, you can only wait until the day the baby is born. But those who can't wait to know, do you want to ask if the hCG value doubles more than once, is it a boy? Does a high hCG value mean a boy is born? Does a doubling of hCG mean a boy is pregnant? According to the hCG data used by the British Pregnancy Research Association for reference only, it is: 3 weeks postmenopause: 5 weeks - 50 mIU/ml, 4 weeks postmenopause: 5 - 426 mIU/ml, 5 weeks postmenopause: 18 - 7,340 mIU/ml, 6 weeks postmenopause: 1,080 - 56,500 mIU/ml, 7 - 8 weeks postmenopause: 7, 650 - 229,000 mIU/ml, 9 - 12 weeks postmenopause: 25,700 - 288,000 mIU/ml, 13 - 16 weeks postmenopause: 13,300 - 254,000 mIU/ml, 17 - 24 weeks postmenopause: 4,060 - 165,400 mIU/ml, 25 - 40 weeks postmenopause: 3,640 - 117,000 mIU/ml. Postmenopausal women: <9.5 mIU/ml hCG Less than 5mIU/ml is a negative reaction, not pregnancy, any total over 25mIU/ml is a positive reaction, pregnancy. If pregnant, 85% of pregnant women, the total amount of hCG in the blood, will double every two or three days. If hCG does not increase at this rate, it means that pregnancy is unsuccessful. It is important to note: do not rely too much on hCG data. A normal pregnancy may have low hCG, which may lead to a normal baby. Low hCG may cause: miscalculation of menstrual period, unsuccessful pregnancy, miscarriage, ectopic pregnancy. High hCG may cause: miscalculation of menstrual period, hydatidiform mole, twins or twins. Appreciate rapidly during the first 8 weeks of pregnancy to maintain the pregnancy. After about 8 weeks of pregnancy, HCG levels gradually decrease until they are relatively stable at about 20 weeks. There is no scientific data to prove that the doubling of hCG means you are pregnant with a boy. If you pay attention to the balance of diet and healthy life, you will have a happy baby. Blood HCG pregnancy test Blood HCG pregnancy test (human chorionic gonadotropin) is the growth hormone "pregnancy test" that is known and most commonly used by obstetricians and gynecologists and nurses. It is composed of α and β dimers of glycoprotein. After a woman becomes pregnant, HCG will be present in her blood and urine. There are still many deviations in the accuracy of early pregnancy test strips. Women do their own pregnancy tests at home without professional guidance, and the test results are generally only 75% accurate. If the test is carried out under the guidance of a doctor, the correct use of the early pregnancy test paper can be guaranteed, and the test accuracy will be higher. Although many types of early pregnancy test strips indicate that women can take a pregnancy test one day after missing their normal menstrual period, in fact, it does not necessarily mean that the rate at which pregnant women secrete HCG hormone is the same. Therefore, we would recommend only using the more accurate blood HCG test. HCG (human chorionic gonadotropin) is the growth hormone most commonly used as a "pregnancy test" by obstetricians and gynecologists and nurses. When symptoms of pregnancy appear, you must go to the hospital for blood tests, HCG tests, B-ultrasound tests, urine tests and other relevant tests to confirm whether you are really pregnant. If you are really pregnant, determine whether it is intrauterine or ectopic pregnancy, and then take corresponding measures. Don't make a decision on your own and judge that you are pregnant based on some symptoms. After a woman becomes pregnant, an increase in β-HCG in the blood can be detected from the 9th to 11th day after fertilization, and it rises rapidly in the first 8 weeks of pregnancy to maintain the pregnancy. After about 8 weeks of pregnancy, HCG levels gradually decrease until they are relatively stable at about 20 weeks. The blood HCG pregnancy test can detect pregnancy earlier. Generally speaking, urine HCG tests such as early pregnancy test strips can only be tested one week after the menstruation stops, while blood HCG pregnancy tests can usually be tested one or two days after the menstruation stops. This can advance the time of confirming pregnancy, so that corresponding preventive measures can be taken against pregnancy earlier. The blood HCG test refers to human chorionic gonadotropin. The early pregnancy test mainly tests the HCG hormone in the urine. Generally, the trophoblast metabolism will cause the HCG hormone in the urine to increase after 6 days of pregnancy. Therefore, if your menstruation is regular, to confirm pregnancy, it is recommended to test at least 7 days after obvious menstruation has stopped. The best time to check blood HCG is 8-10 days after intercourse. At this time, the blood contains a higher HCG value and the test is more accurate. For those who suspect they are pregnant, it is recommended to use this method for testing within this time frame. |
