The patient's TCT generally cannot detect whether they have vulvar cancer. TCT can also be referred to as liquid-based thin layer cytology, primarily examining the exfoliated cells scraped from the cervix to see if they are malignant. A negative result indicates that there is no cervical cancer.

If one wishes to check for vulvar cancer, gynecological examinations can be conducted. These include blood tests for tumor markers, vaginal ultrasound, and vaginal tissue biopsy. Through these tests, any abnormalities in the vulva can be detected. It is advised that patients seek timely examination and treatment based on the disease.
