A pregnancy test after dinner usually does not affect the results of the test, which is usually a test of the hormone levels in the body, and is related to the length of the pregnancy, rather than whether or not you have eaten. Pregnancy test is usually to detect the human chorionic gonadotropin content in the body, including blood and urine test two ways, because the urine test is cheap, convenient and used by most women of childbearing age. However, in some patients, due to low hormone levels during early and early pregnancy, there is a possibility of false-negative urine tests, but blood tests are more accurate. When applying the urine test, morning urine is generally more accurate because it is concentrated, but as pregnancy progresses, the level of human chorionic gonadotropin in the body rises significantly, and the hormone content within the urine also rises, thus increasing the probability of being able to detect a positive test.
