Blood hcg test

The blood hcg test is mainly used to measure the HCG value contained in a woman's blood and to determine whether the woman is pregnant. The blood HCG test itself is more accurate than the traditional urine HCG test, with a smaller error during testing, and the test time can be advanced. Let’s take a look at the knowledge introduction of blood hcg test.

The blood hCG test actually refers to the production of human chorionic gonadotropin. When the early pregnancy test paper appeared, the main detection mode was the blood hCG test in people's urine. Under normal circumstances, it is six days after conception that the syncytial trophoblast will have a relatively high secretion, thus causing an increase in blood hCG hormone. So we should pay attention to this.

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.

When doing a blood hcg test, if you want to do it reasonably, the best time is about eight or ten days after having sex. At this time, the blood contains a very high hcg test value, so the test will be more accurate. I hope we can understand this.
