Women who want to know if they are pregnant after sexual intercourse can usually go to the hospital ten days after intercourse to have a blood test for HCG content. This is the most accurate and earliest method to detect early pregnancy. Recently, a woman asked how to read the HCG measured and how much it indicates pregnancy. If the HCG value is slightly higher on the blood test, is it pregnancy?
The normal value of blood HCG is generally below 10 μ g/L, and the normal standard value of β - hCG should be below 3.1 μ g/L. Therefore, when the test result value is above 5, it is considered that there is a possibility of pregnancy. If it is above 10, pregnancy can be basically confirmed. Therefore, if the blood HCG value is slightly higher than 3.1 but does not exceed 5, it is temporarily uncertain whether pregnancy is possible. It is recommended to have another test after a week.
The examination of blood HCG usually involves obtaining a blood test certificate from the hospital, and then going to the laboratory for medical staff to draw venous blood from the arm for examination. Before the blood test, there is no need to fast or fast. Normally, the blood test can be completed in one day to obtain the results. However, blood HCG can only check whether pregnancy is present, and cannot determine whether it is intrauterine pregnancy. Therefore, after 5 weeks of amenorrhea, B-ultrasound examination is needed to confirm.
HCG secretion rapidly increases after fertilization, reaching its peak at week 8 of pregnancy, and then gradually decreases until it stabilizes after weeks 18 to 20. HCG can promote the conversion of androgens in women's bodies into estrogen through aromatase, and further stimulate progesterone synthesis. Progesterone can protect the endometrium and form a natural barrier to protect the fetus from external invasion, while providing support for growth and development.
