Pills inserted the night before the test can affect the results of the test because the inserted medication can affect the vaginal flora and lead to inaccurate test results. Therefore, if a patient has had medication inserted the night before the test, it is usually recommended that the test be repeated 3 days later. The leukorrhea is an important basis for determining whether there is disease in the vagina or uterus. Observing the leukorrhea from time to time helps women to detect problems as early as possible. Normal leukorrhea is a white, thin paste with no odor. The amount and nature of leukorrhea can be affected by the secretion of estrogen in the body, genital congestion, and pathogenic bacterial infections. Before checking the leukorrhea, patients should also pay attention to the following: 1. Avoid taking a bath and vaginal medication before the examination to avoid damaging the microenvironment of the vagina and affecting the examination results; 2. Avoid sexual intercourse within 24 hours before the examination to avoid semen residue, which can damage the microenvironment of the vagina and affect the examination results; 3. 4. 1 week before the examination, patients should maintain a light diet, drink more water, avoid smoking and alcohol, and avoid spicy and stimulating food.
