How to diagnose venereal disease

One: 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. Of course, in order to ensure the accuracy of the examination, we must choose the formal hospital for diagnosis.

Second: immunohistochemical examination: commonly used peroxidase anti peroxidase method (Pap), showing the virus protein in sexually transmitted diseases, in order to prove that there is virus antigen in wart damage. When HPV protein was positive, there was weak positive reaction in the superficial epithelial cells of STD.

Third: verruca virus antibody test: so far, it is difficult to detect HPV by traditional virus culture and serological techniques, and the main experimental diagnostic technique is nucleic acid hybridization. The PCR method developed in recent years has the advantages of specificity, sensitivity, simplicity and rapidity, which opens up a new way for HPV detection.
