There is no need to fast to check chorionic gonadotropin, and it can be done anytime you go to the hospital to have blood drawn. The rise in chorionic gonadotropin is largely related to pregnancy. Chorionic gonadotropin increases during pregnancy, and during early pregnancy as the duration of pregnancy increases, the level of the hormone rises significantly, and in the fastest stage it can increase by 0.7 times per day, and at its peak it can reach about 200,000, then it gradually decreases around 8-10 weeks, and then it will remain at a relatively stable level until the end of the pregnancy, and the results of the test are mainly influenced by the duration of pregnancy, and there is no influence on what you eat or drink. The result of this test is mainly affected by the time of pregnancy and has nothing to do with food. During early pregnancy, chorionic gonadotropin can be monitored to indirectly understand the development of the embryo, and in the case of pregnant women with preeclamptic miscarriage, it is necessary to repeat the test several times before it can be done.
