What is the normal value of hcg in early pregnancy

During early pregnancy, which is usually one month or 30 days later, women will experience symptoms such as drowsiness, anorexia, vomiting, and lack of energy. Some women's reactions are not very obvious. Because everyone's physique and age are different, the reactions to early pregnancy will also be different. So what is the normal value of hcg in early pregnancy?

Blood HCG concept:

The HCG blood test is currently the earliest and most accurate way to test whether a woman is pregnant. The HCG blood test is usually done 8-10 days after sexual intercourse to determine whether a woman is pregnant by drawing blood to test for HCG. Human chorionic gonadotropin (hCG) is a glycoprotein secreted by trophoblast cells of the placenta and is composed of two subunits, a and b. hCG enters the maternal blood after fertilization and proliferates rapidly until the 8th week of pregnancy, then slowly decreases in concentration until the 18th to 20th week, and then remains stable. The HCG blood test is a quantitative test of HCG in the blood to understand whether pregnancy is possible.

Blood HCG is an important method for early diagnosis of ectopic pregnancy. Since the HCG level in the patient's body during ectopic pregnancy is lower than that during intrauterine pregnancy, a highly sensitive radioimmunoassay is required to measure blood HCG. This experiment can perform quantitative measurements.

Pregnancy test

The HCG blood test determines whether a woman is pregnant by measuring the HCG level in her blood. Compared with traditional urine HCG, blood HCG is more accurate, has smaller errors, and can be tested earlier. In order to detect the accuracy of pregnancy, doctors generally recommend a blood HCG early pregnancy test. "Quantitative" testing of HCG values ​​in blood can respond to pregnancy more sensitively and accurately than the ordinary "qualitative" testing of urine with early pregnancy test strips, with an accuracy rate of over 99%. In addition, for multiple pregnancies, ectopic pregnancies, abnormal fetal developmental retardation, hydatidiform mole, certain endocrine diseases or tumors, the blood HCG value can be combined with the clinical condition and other examination results, and a correct judgment can often be made through comprehensive analysis.

Blood HCG early pregnancy test (human chorionic gonadotropin) is the "pregnancy test" hormone that is familiar and most commonly used by obstetricians and gynecologists. It is composed of glycoproteins of α and β dimers. When a woman becomes pregnant, HCG will be present in her blood and urine. There are still many errors in the accuracy of early pregnancy test strips. When women do self-pregnancy tests at home, they are done without professional guidance, and the test results are generally only 75% accurate. If the test is performed under the guidance of a doctor, it can ensure the correct use of the early pregnancy test paper and the test accuracy will be higher.

Although many types of early pregnancy test strips indicate that women can do a pregnancy self-test one day after missing their normal menstrual period, in fact not all pregnant women release HCG hormones at the same rate and time. Therefore, we would recommend only using the more accurate blood HCG test. HCG (human chorionic gonadotropin) is the "pregnancy test" hormone that obstetricians and gynecologists are familiar with and most commonly used. After a woman becomes pregnant, an increase in β-HCG can be detected in her blood from the 9th to 11th day after fertilization, and it increases rapidly in the first 8 weeks of pregnancy to maintain the pregnancy. After about 8 weeks of pregnancy, HCG gradually decreases until it reaches a relative stability around 20 weeks.

When symptoms of pregnancy appear, you must go to the hospital for blood HCG tests, B-ultrasound tests, urine tests and other corresponding tests to confirm whether you are really pregnant. If you are really pregnant, determine whether it is an intrauterine pregnancy or an ectopic pregnancy, and then take appropriate measures. Never make a decision on your own and determine that you are pregnant based on some symptoms.

The blood HCG early pregnancy test can detect pregnancy earlier. Generally speaking, urine HCG tests such as early pregnancy test strips can usually only be performed one week after the menstrual period has ended, while blood HCG early pregnancy tests can often be performed one or two days after the menstrual period has ended. This can advance the time of confirming pregnancy, so that appropriate countermeasures can be taken earlier for the pregnancy.

The blood HCG test refers to human chorionic gonadotropin. The early pregnancy test strip mainly detects the HCG hormone in the urine. Generally, the syncytial trophoblast secretes an increase in the HCG hormone in the urine 6 days after conception. Therefore, if you have regular menstruation, it is recommended to test at least 7 days after the menstruation has obviously stopped to confirm pregnancy.
