The diagnosis of genital warts is mainly based on clinical diagnosis by an experienced physician and can be supplemented by other tests such as acetic acid test, histopathology, PCR, etc. Acetic acid test: A solution of 3% to 5% acetic acid is applied to the skin suspected of being infected with HPV, and the area is usually whitened after 1-2 minutes. Advantages: The white reaction can occur in clinically visible lesions or in areas of HPV infection without visible warts. The white acetate test can make inconspicuous lesions visible to the naked eye. Disadvantages: The method has low specificity and often gives false positive results in lesions such as mucosal epithelial thickening due to chronic inflammatory reactions, contact dermatitis, and genital herpes. The positive results of the white acetate test alone do not confirm that it is a condyloma acuminatum, subclinical infection. The negative acetic acid test does not exclude condyloma acuminata and subclinical infections, which need to be confirmed by other methods of testing.
