The white acetic acid test is a common method to check for warts. Warts are sexually transmitted diseases due to human papillomavirus infection, and the keratin produced by epithelial cells after human papillomavirus infection is different from normal cells, which can be whitened by glacial acetic acid at this time. After applying 5% glacial acetic acid to the lesions, the lesions will turn white after 2-5 minutes of observation, and the surrounding normal tissue will not change color. If you have a positive acetic acid test, there is a high probability of acquiring a condyloma. 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.
