What does a dual-stain test mean?

Generally, dual-stain testing is an auxiliary examination used to detect cervical precancerous lesions. The specific details are as follows:

Dual-stain testing is an adjunctive method for cytological diagnosis, commonly used to assess cervical tumor markers. It primarily involves collecting exfoliated cells from the cervical os and performing pathological analysis to determine the presence of cervical precancerous lesions or cervical cancer. This testing method combines cytology and histology techniques, enabling a more accurate diagnosis of potential malignant changes. Dual-stain testing of the cervix allows for early detection of cervical cancer, thereby improving treatment outcomes and reducing patient suffering.

Dual-stain testing is typically performed 3 to 7 days after the end of menstruation. Patients should avoid sexual intercourse, vaginal douching, or using vaginal medications for at least 3 days prior to the test to prevent interference with results. Individuals experiencing symptoms or discomfort should seek timely medical attention and follow standardized treatment under a physician's guidance, which helps promote recovery.
