HPV, or human papillomavirus, is a virus that can lead to condyloma acuminata and common warts in men. There is no clear method of self-testing, so if a patient finds abnormal signs in a body part, please seek medical attention for examination. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. The skin protrusions of condyloma acuminata are mainly located near the external genitalia and the anus, such as the male glans, perineum, and perianal area, and can appear coronary or cauliflower-shaped, usually without obvious symptoms. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. If it turns white, it indicates a positive vinegar white test. This method is more helpful in confirming HPV infection, especially subclinical infection, but it is necessary to exclude epithelial thickening due to chronic inflammation caused by other reasons, which may be false positive; 2. Histochemical examination: with the help of a microscope, observe whether the specific antibodies that are labeled appear to change color. This method has strong specificity and rapid results; 3, cytopathological examination: body fluids, mucous membranes, lesions and other tissues can be collected and observed under the microscope to see if there is an infection; 4, quantitative genotyping detection system: the virus is detected by gene chip to analyze the type of virus and then guide the next step of diagnosis and treatment; 5, molecular biology examination: such as PCR (polymerase chain reaction), nucleic acid Molecular hybridization techniques, the former is simple and rapid, this method is commonly used in clinical practice to detect HPV virus, the latter is also an important means of detection, but it is not easy to operate, so the clinical application is less; 6, immunohistological examination: when HPV protein positive, superficial epithelial cells can appear color change, that is, light red change. This method is not very sensitive and has a low detection rate.
