Is the hcg test accurate for ectopic pregnancy?

Is the hCG blood test for ectopic pregnancy accurate? This is what many pregnant women want to fully understand, because every pregnant woman wants to be healthier during pregnancy, so when they have problems of one kind or another, they want to fully understand whether the hCG blood test for ectopic pregnancy is accurate? The following content provides a detailed introduction so that you can have a comprehensive understanding.

The 48 hours after a healthy blastocyst is transplanted into a woman's uterus is the most critical moment for determining blastocyst implantation and pregnancy. Many women feel very scared after blastocyst transplantation, fearing that the blastocyst will not implant or an ectopic pregnancy will occur. Thai test tube experts said that although women should rest more during this period, they are not required to lie still. Going to the toilet and walking slowly are fine, but don't feel tired. In fact, there are many factors that affect the implantation of the blastocyst, such as the quality of the blastocyst, whether the intrauterine environment is good, the location where the doctor transplants the blastocyst into the female uterus, etc. Therefore, the factors that cause the blastocyst to fail to implant are not all caused by the woman’s behavior after transplantation.

Of course, whether it is natural conception or after blastocyst transfer, the first priority is to determine whether the pregnancy is normal as soon as possible. This can be determined through "early pregnancy test paper" and "blood HCG test". So which of these two methods is more accurate?

Early pregnancy test strips are products designed to help women detect whether they are pregnant. Early pregnancy test: drop urine into the detection hole on the test paper. If a colored band appears in the control area of ​​the test paper (some test papers appear red, some test papers appear blue), it indicates negative, indicating that you are not pregnant; conversely, if a clear colored band appears in the detection area, it indicates positive, indicating that you are pregnant.

The principle is: the HCG (human chorionic gonadotropin) test strip is mainly made based on the principle of immunochromatography double antibody sandwich method, which can measure HCG in urine samples within 3 minutes. During the test, when the urine sample is siphoned through the colloidal gold-labeled antibody, an antigen-antibody colloidal gold complex is formed. The complex continues to crawl and passes through the coated anti-HCGα subunit Mcab to form a double antibody sandwich colloidal gold complex, which appears as a color band at the coating line. The excess colloidal gold antibody continues to crawl and forms a colloidal gold immune complex with the sheep anti-mouse control line, which appears as a color band. Using colloidal gold as an indicator marker, the HCG concentration in urine is tested to confirm whether a woman is pregnant.

Is the hCG test for ectopic pregnancy accurate? After understanding the above comprehensive introduction, I believe that many pregnant women have already had more knowledge. The accuracy of the hCG test for ectopic pregnancy is still relatively high. Therefore, for many pregnant women, they can take this method to check, and the results of the test are relatively accurate.
