It begins to rise 8-10 days after fertilization and can be detected by drawing peripheral blood from a vein with a high degree of accuracy. It is simple and convenient to have the blood drawn at the hospital and does not require fasting. This test not only confirms pregnancy, but also provides a comprehensive analysis of the development of the embryo based on the dynamic changes of this value, and is an important indicator for the early determination of ectopic pregnancy, which is widely used in early pregnancy.
