The positive Schiller test means that cellular changes were found in the internal region of the vagina, which may suggest the presence of benign changes, such as a poorly placed IUD, some inflammation, condyloma, Syphilis, HPV, or even, cervical cancer..
However, the Schiller test can give a false positive result, which is why pap smears are usually requested in their place, as a way of investigating cervical cancer, because they give clearer and more concrete results.
Another exam similar to this is the acetic acid test where the same principle of staining of the vagina and cervix is used, in which case the region should be whitish. Where white is most evident, there are signs of cellular changes. This test is particularly suitable for women who are allergic to iodine, and cannot do the Schiller test.
What it is and what it is for
The Schiller test is a diagnostic test that consists of applying an iodine solution (Lugol) to the entire internal region of the vagina and cervix. This solution reacts with the cells in the region and, when they turn brown after application, the result is said to be normal. In cases where the solution fails to color some specific areas, it means that there is some change in these areas.
This test is performed on all sexually active women as a routine test and in those who have any symptoms such as pain, discharge or bleeding after sexual intercourse. In low-income cities, this test can also be used to screen for cervical cancer. The test can also be done immediately during a biopsy to make it clearer where the tissue should be removed for analysis.
