Purpose of blood hcg testing

The traditional method of testing pregnancy is through pregnancy test sticks, physical changes, irregular menstruation, etc. With the development of science and technology, blood hCG testing uses a scientific, reasonable and effective method to detect the value in a woman's blood to accurately determine whether she is pregnant. This is more efficient and accurate than traditional testing methods, and the error is smaller. So what is the purpose of blood hCG? Let’s take a look at it together below.

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

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 measures can be taken for the pregnancy earlier.

If both husband and wife are eager to have a baby, they can go to the hospital for a blood hCG test one week after having sex. The accuracy of the blood hCG test can let both husband and wife know whether they are pregnant more quickly. Of course, before the test, you must maintain a good mood and prevent major emotional fluctuations to avoid errors in the test. At the same time, you must also be mentally prepared to welcome the arrival of the newborn.
