What method does China use to check condyloma acuminatum?

Examination method of condyloma acuminatum 1. Pathological examination: Pathological examination is a method with high accuracy in condyloma acuminatum examination, but it is traumatic to some extent. It starts with the symptoms of condyloma acuminatum and determines whether it is condyloma acuminatum through inspection. Pathological examination mainly showed dyskeratosis, high spinous hypertrophy, papilloma-like hyperplasia, thickening and lengthening of epidermal process, and its proliferation degree could be similar to pseudoepithelioma.

2. Immunohistochemical examination: The virus protein in condyloma was displayed by peroxidase anti-peroxidase method (PAP) to prove the existence of virus antigen in warts. When human papillomavirus protein is positive, the superficial epithelial cells of condyloma acuminatum can have reddish positive reaction.

3. Histochemical examination: Take a small amount of diseased tissues to make smears and stain them with specific antibodies against human papillomavirus. If there is a virus antigen in the lesion, the antigen and antibody bind. In the peroxidase anti-peroxidase (PAP) method, the nucleus can be dyed red. This method is specific, rapid and helpful for diagnosis.

4. Acetic acid white test: The principle of this test is the result of protein and acid condensation whitening. Keratin produced by human papillomavirus infected cells is different from that produced by normal uninfected epithelial cells, and only the former can be decolorized by acetic acid. However, the acetic acid white test is not a specific test, and false positives are more common.
