What should a patient avoid using prior to a Pap smear test?

Prior to a Pap smear test, patients should avoid using over-the-counter (OTC) vaginal creams because these products can interfere with the accuracy of the results. Specifically, vaginal creams can alter the natural environment of the cervix or introduce substances that might obscure the cell samples collected during the Pap smear. The test aims to detect abnormal cervical cells, and the presence of these creams can lead to false results, either by masking abnormalities or by causing inflammation.

In contrast, liquid medications, antibiotics, and hormonal supplements generally do not have the same immediate and direct impact on the cervical cells being assessed. While antibiotics may affect the vaginal flora, they typically do not interfere with the Pap smear itself. Hormonal supplements and other medications do not alter the cell structure or the cytology needed for the test's evaluation. Therefore, the focus on avoiding OTC vaginal creams specifically is crucial for ensuring the reliability of the Pap smear results.
