One: acetic acid white test: use 3-5% acetic acid to smear the wart for 2-5 minutes, the lesion becomes white and slightly uplifted, and it may take 15 minutes for anal lesions. The sensitivity of acetic acid white test to detect HPV is very high, and it is better than routine test to observe histological changes. However, occasionally in the cases of epithelial thickening or traumatic abrasions, false-positive and false-positive signs of whitening appear unclear and irregular. If the doctor's experience is relatively rich, the basic is to be able to accurately determine whether it belongs to condyloma acuminatum.

Second: histochemical examination: a small amount of diseased tissue was made into smear and stained with specific anti human papillomavirus antibody. If there is a viral antigen in the lesion, the antigen and antibody are combined. In the peroxidase anti peroxidase PAP method, the nucleus can be dyed red. This method is specific and rapid, which is helpful for diagnosis.

Third: immunohistochemical examination: commonly used peroxidase anti peroxidase method, namely PAP, shows the virus protein in condyloma to prove that there is virus antigen in the lesion of condyloma. When HPV protein was positive, weak positive reaction of light red appeared in the superficial epithelial cells of condyloma acuminatum.
