Preparation for routine gynecological screenings involves several steps. For a Pap smear, it is advisable to avoid intercourse, douching, or using vaginal medications for 48 hours before the test. Wearing comfortable clothing and scheduling the appointment when not on your menstrual period can also help. For mammograms, avoid using deodorants or lotions on the day of the test as they can interfere with the results. Discussing any concerns or symptoms with your healthcare provider beforehand can ensure a comprehensive evaluation.
