Another internal genital warts test is called Colposcopic examination. This is done by inserting an instrument called speculum to separate the vaginal walls. Once this is done, a solution of acetic acid is applied on the walls of the vagina and on the cervix. Any warts that are growing in the area should turn out visible to the eye but if not, then a special dye is applied to the area. If this genital warts test still does not produce a conclusive result, then a cell sample is taken for examination. The process is done with the use of a wooden spatula or a swab. Further testing can be done if you still want to know more about possible infections.
