Unfortunately, there is no do-it-yourself test available to test for genital warts. If you suspect you may have genital warts, you will need to visit your doctor for an examination. The doctor who carries out the examination will check your genital area and anus, both through an internal and external examination. This is the only way that genital warts can be conclusively diagnosed. If the warts are not yet visible, it is likely that you will need to go back for a secondary examination.
