The Schiller test is a diagnostic test that involves applying an iodine solution, Lugol, to the inner region of the vagina and cervix and aims to verify the integrity of cells in this region.
When the solution reacts with cells in the vagina and cervix and turns brown, the result is said to be normal, but when it cannot color a specific area, it is a sign that there is a change, which requires more specific tests.
- Typically.
- The Schiller test is done during colposcopy and is therefore indicated for women who are sexually active or who have had abnormal results on the preventive test.
- The Pap test.
O teste de Schiller é indicado pelo ginecologista para as mulheres sexualmente ativas como exame de rotina, nas que apresentem algum sintoma como dor, corrimento ou sangramento após as relações sexuais ou que tiveram resultados alterados no exame de papanicolau, também conhecido como exame preventivo.
Além disso, o médico pode solicitar o exame quando há suspeita de alguma doença ginecológica, como HPV, sífilis, inflamação vaginal ou câncer de colo de útero. Nesses casos, além da realização do teste de Schiller, pode ser necessária a realização de exames complementares, como biópsia, ultrassonografia transvaginal e colposcopia, por exemplo.

The Schiller test is said to be positive when, after setting up lugol, the tissue does not absorb all the lugol and yellowish areas can be seen in the cervix, indicating that there is a change in the cells, which may suggest the presence of benign or malignant changes, such as:
However, the Schiller test can give a false positive result, so cervical smearing is usually requested instead, as a means of cervical cancer research, as it gives clearer and more concrete results. In addition, to confirm the positivity of the Schiller test and identify the cause of the change, your doctor may order a biopsy to show the characteristics of tissue and cells.
Another test similar to this is the acetic acid test, where the same principle of coloration of the vagina and cervix is used, in which case the area should be whitish. Where the target is most obvious, there are signs of cellular changes. This test is especially suitable for women who are allergic to iodine and therefore cannot undergo the Schiller test.
Schiller’s test is said to be negative when, after the lugol’s coloration, all vaginal mucosa and cervix have been colored, without a yellowing region, indicating that there is no change in the woman’s genital area, i.e. Ordinary.
