Strictly speaking, the acetic acid white test is used to determine warts, not white vinegar, and if the test is positive, it suggests the possibility of the presence of warts. The acetic acid white test involves soaking a gauze or cotton ball in an acetic acid solution and applying it to the area suspected of having warts and subsequently observing the changes. If white color appears on the applied area, it is positive, and if there is no change, it is negative. A positive test suggests the possibility of wart infection. However, the acetic acid white test can only be a rough judgment, the diagnosis also needs to be combined with clinical manifestations, human papilloma virus DNA testing, and other judgments, but also through the histopathology of the test. When the diagnosis of HPV infection is confirmed, it should be actively treated under the guidance of the doctor.
