γγ Inaccurate. A blood test cannot confirm the diagnosis of condyloma acuminatum.γγThe reasons are as follows: HPV infects humans mainly through direct or indirect contact with contaminated objects or through sexual transmission. After the virus invades the body, it stays in the skin and mucous membranes at the site of infection and does not produce viraemia. Within 1 to 2 months after the appearance of the infected lesion, the corresponding antibody is produced in the blood against the infected virus, and at this time, if the blood is drawn for examination, the result will be positive, and the positive rate is about 50-90%. HPV has more than 200 types and can cause more than 10 kinds of diseases, such as flat warts, common warts, condyloma acuminata and other diseases. An ordinary person with a wart will probably have a positive blood test for HPV. However, a positive result does not mean that the person has an STD or condyloma. This is why a blood test cannot verify whether or not a person has warts.
