What is the meaning of 12 day hcg in IVF?
IVF is an assisted reproductive technology that fertilizes sperm and eggs in vitro, and then implants the fertilized eggs into the mother's uterus to achieve the purpose of pregnancy and fertility. And hcg is an indicator in test tube babies, which is the abbreviation of human chorionic gonadotropin. It is a hormone secreted by early embryonic cells and one of the important indicators in early pregnancy.
The role of hcg in test tube baby
In the process of ivf, hcg is used to confirm the success of pregnancy. After the fertilized egg is implanted into the uterus, if the embryo is successfully implanted and develops well, the cells in the embryo will continue to secrete hcg and enter the mother's body through blood circulation. Therefore, by detecting the concentration of hcg in urine or blood in early pregnancy, we can judge whether pregnancy is successful or not.
Generally speaking, the concentration of hcg will continue to rise within 10 to 14 days after conception, and gradually decrease after reaching the peak. Once the hcg test is carried out about 12 days after pregnancy, it can clearly determine whether the pregnancy is successful.
Flow and method of hcg detection in test tube infants at 12 days
12 day hcg detection in test tube infants is usually divided into two methods: urine detection and blood detection.
Urine test is commonly used as a family pregnancy test paper, which can be tested at home. The method of use is very simple. Just drop a few drops of urine on the test paper and wait for a few minutes to see if there are two lines with different depths on the test paper. If there are two lines, it means that the hcg concentration is high enough and the pregnancy is positive; If there is only one line or no line, it is negative, indicating that she is not pregnant.
Blood testing is generally carried out in hospitals, which is more accurate and reliable. The doctor will provide an application form for blood testing, and the patient will go to the inspection center of the hospital or relevant departments for blood collection. After blood collection, the sample will be sent to the laboratory for detection of hcg concentration, and the result will be fed back to the patient after a certain time. The blood test is relatively accurate, which can clearly measure the specific value of hcg and help doctors evaluate the embryonic development.
Summary
12 day hcg of test tube baby is an important indicator in the process of test tube baby, which is used to confirm whether pregnancy is successful. Hcg is a hormone secreted by embryos, and its concentration can be determined by urine or blood tests. Urine testing can be carried out at home, while blood testing needs to be carried out in the hospital. No matter which method is used, the detection of hcg can help doctors evaluate the development of embryos and provide important reference for the successful pregnancy of test tube babies.
