A blood test for early pregnancy does not require an empty stomach. If a woman of childbearing age has a regular menstrual cycle and has not had her period for 1 week, she is more likely to be pregnant and can determine whether she is pregnant by testing with a urine early pregnancy test or by taking a blood test for human chorionic gonadotropin. If pregnancy is confirmed by the test, fasting is required to establish a maternal health handbook. There are more items to be checked during the establishment of the handbook, including liver and kidney function, thyroid function, screening for related infections and eugenics checkups, etc. It is recommended to skip breakfast and avoid sexual intercourse and strenuous exercise during the third month of pregnancy to avoid miscarriage.
