A pregnancy test does not require fasting because it is a blood test for chorionic glandular hormone, a hormone that is not affected by eating or drinking. For the diagnosis of early pregnancy, a blood test for chorionic gonadotropin is the most accurate test. A pregnancy test can also be used to initially detect pregnancy. A pregnancy test with two dark bars indicates pregnancy, while a single bar indicates that you are not pregnant. If there is one dark bar and one light bar on the pregnancy test, it means a weak positive result and there is a high chance of pregnancy. There are many clinical methods to diagnose early pregnancy: first, vaginal ultrasound examination after 35 days of menopause to see if there is a gestational sac in the uterine cavity, so as to confirm whether it is an intrauterine pregnancy, and also to exclude ectopic pregnancy. Secondly, a urine test can be done one week after menopause and if the result is positive, it indicates pregnancy. If blood is drawn for a pregnancy test you need to fast because there are so many tests that have items that require fasting.
